How do I fix the Windows blue screen errors?

Before fixing a Microsoft Windows blue screen or blue screen of death error (BSoD) you must first identify what error it is. Since there are different blue screen errors.

Note: If you're getting a blue screen and then your computer immediately reboots without being able to read the text in the blue screen, follow the steps below. If you're unable to get into Windows to perform the steps below, boot the computer into Safe Mode.

1. From the Desktop right-click on My Computer.
2. Click the Properties option.
3. In the System Properties window click the Advanced tab or the Advanced system settings link.
4. In Advanced click the Settings button under Startup and Recovery.
5. In the Startup and Recovery window uncheck the Automatically restart check box.
6. Click Ok.

Note: If you're getting a solid blue screen with no white text, you are not encountering a BSoD. It's likely a problem with your video card, monitor, or other hardware. Follow the no display on monitor troubleshooting steps to diagnose this problem.

Blue screen errors

Windows NT, 2000, XP, Vista, and later versions of Windows have a blue screen error that's similar to the example shown below. These error messages often contain more detailed information, and will contain information that can be searched for and found. If you're not getting a blue screen error that looks like the below skip to the next Fatal exception section.

1. Identify the blue screen by locating a line containing all capital letters with underscores instead of spaces, such as the above example, BAD_POOL_HEADER. Write this information down. If you do not see anything written in all caps with underscores like this, skip this step.
2. Get either the STOP: error message at the top of the error, or in the "Technical Information:" portion of the error. For example, in the above error it's STOP: 0x00000019 ... write the first potion of this error message down.
3. Finally, if technical information is shown write down the file and the address.

Once you have the above information you can start troubleshooting the issue. Below are common blue screen errors and links to pages that contain the troubleshooting steps for each of these errors. If your error is not listed in the below section search for the error you wrote down.

BAD_POOL_HEADER
DRIVER_IRQL_NOT_LESS_OR_EQUAL
DRIVER_POWER_STATE_FAILURE INACCESSIBLE_BOOT_DEVICE
IRQL_NOT_LESS_OR_EQUAL
NTFS_FILE_SYSTEM
PAGE_FAULT_IN_NONPAGED_AREA
STATUS_IMAGE_CHECKSUM_MISMATCH
THREAD_STUCK_IN_DEVICE_DRIVER
UNEXPECTED_KERNEL_MODE_TRAP
UNKNOWN_HARD_ERROR

Fatal exceptions

Many of the blue screen error messages you'll encounter with earlier versions of Windows will be fatal exception error messages or Fatal 0E messages. If your blue screen message starts out with A fatal exception 0E ... or An exception ... you're encountering this error. For these blue screen errors follow the fatal exception error troubleshooting steps.

Not a valid Win32 application

File is corrupt, bad, or missing

If the file or program you're attempting to run is corrupt or missing, Windows will be unable to execute the file properly and sometimes generate this error message.

Download files

If you downloaded this file and verified it is complete and compatible with your version of Windows, delete the file and try downloading and running it again. It's possible during the download that the file became corrupted.

Finally, if the second download does not work, try downloading the file from a different webpage. It is possible that the person or company maintaining the website mistakenly uploaded a corrupt version of the file you're attempting download.

Installing a program from a CD or other disk

If you're attempting to install a program and are getting this error, verify that the CD is clean. If the CD is dirty or bad, you could get this error during the install or after the program has been installed because it was not copied properly onto the computer.

Running a program from the computer

If you're running the program from a shortcut on the computer, verify that the program is still on the computer. In some cases if the program is no longer installed on the computer you may get this error.

If the hard drive is corrupted or bad it can also cause working programs to fail either because not all the data can be read from the hard drive or because the program has become corrupted while on the drive. Run scandisk and defrag on the hard drive to check for any potential errors.

Long file name issue

Make sure the program or file you're attempting to run does not contain the same name as the long file name directory it is contained in. For example, executing a file named "program" in the "program files" directory can cause errors in some versions of Windows.

Additionally, if you're attempting to install a program and after the install the program does not work, you may also want to try installing the program in a different directory.

Bad file

Any file can be changed or renamed to be a .exe file. If you're downloading the file, make sure the file is supposed to be a .exe file and that it's not being changed. If you're attempting to create a .exe, file make sure you're compiling the file for Windows and never just rename a file to a .exe file. For example, renaming a .bat file to a .exe file will not make the file an executable file. For a file to become an executable file it needs to either be compiled or converted through a software program designed to convert the file.

File is not designed for your version of Windows

If you're trying to run a program that is not designed for your version of Windows you may get this error. Although many older programs designed to work in older versions of Windows will work with new versions of Windows, unfortunately, not all programs will work.

• If the program is an older MS-DOS program or early Windows program you may get this error.
• If the program is designed for a 64-bit version of Windows and you're running it in a 32-bit version of Windows, it will not work and generate this error.

Getting old MS-DOS games to run in Windows.

File is a virus, worm, or other malware file

This error can be generated by a file that is a virus, worm, Trojan, or other malware file. Often, this will be caused because the virus scanner installed in the computer will not allow the file to be installed or run. Try scanning the file to verify it is not a virus or infected.

If the file has been checked and is clean, it is still possible that the virus protection program or another program installed on the computer is causing issues during the install or execution of the program. Boot the computer into Safe Mode and try running the program; booting the computer into Safe Mode makes sure nothing is running in the background that could be causing this issue.

Hardware incompatibility

If you're getting this error during the installation of a program it's also possible that the CD-ROM drive or the drive you're installing the program from is not compatible with Windows or has drivers that are not compatible with Windows.

Download the latest drivers for your CD drive or other drive through our drivers page.

Windows restarts without warning

       

 

 

Software issue or error

With the introduction of Windows XP Microsoft designed Windows to automatically reboot each time an error occurs such as a BSoD. Although this may be nice for errors that do not occur often, users who have a re-occurring error may want to identify the error to troubleshoot it. Below are the steps on how this feature can be disabled and enabled in Windows XP, Vista, 7, and 8.

1. From the Desktop right-click on My Computer.
2. Click the Properties option.
3. In the System Properties window click the Advanced tab or the Advanced system settings link.
4. In Advanced click the Settings button under Startup and Recovery.
5. In the Startup and Recovery window uncheck the Automatically restart check box.
6. Click Ok.

Now if the computer generates an error it should not automatically restart and should display an error message, most likely a BSoD.

• How do I fix the Windows blue screen errors?

Hardware issue or error

Caution: Some of the steps below require you open your computer. While in the computer, be cautious of ESD.

Any failing hardware component in your computer could cause your computer to unexpectedly generate an error or reboot without warning. If you have recently attempted to add a new hardware device, remove that device to make sure it is not causing your issues.

Make sure you are not encountering any hardware conflicts by viewing Device Manager for errors.

New drivers can also cause this issue, if you have recently performed any hardware driver updates you may want to try an earlier version of the drivers. Additional information and help with computer drivers can be found on our drivers page.

If you have updated drivers and removed any hardware that could be causing this issue and continue to experience random reboots, it's possible that the memory is bad in the computer.

• How can I test my memory to determine if it is bad?

Finally, hardware devices that are not installed properly in the computer can also cause random reboots. Make sure all the cables and expansion cards are connected properly to the computer. The best way to determine this is to disconnect and reconnect all cables and expansion cards.

Computer virus

Computer viruses such as the blaster virus are written to reboot your computer without warning. Usually these viruses make the computer reboot every 5, 10, 15 or 30 minutes after the computer has booted.

If you believe your computer may be infected with a virus or are uncertain if your computer is infected with a virus make sure your virus scanner definitions are up to date.

• How do I update my antivirus program?

Heat related issue

Many computer today are designed to turn off or automatically reboot if the computer, processor, or other device in your computer gets to hot. If you have heard any abnormal noises coming from your computer recently such as a high squealing this could indicate a fan may be failing in your computer.

First, verify the fan on the power supply is working by examining the back of the computer and seeing if the fan is moving and moving smoothly. For all other fans in the computer you need to either open the computer and verify all fans are working, e.g. processor fan and case fan.

A temperature gun like that shown in the picture can also be used to help gauge how hot components or integrated circuits are running the computer.

Tip: If your BIOS monitors the RPM of the fans enter CMOS Setup and verify it does not report any errors.

Note: If this is a laptop computer, there is still a fan located on one of the sides of the laptop that can be checked. Make sure this fan is blowing or that you can feel hot air coming from the laptop. You may also consider getting a cooler pad if you find your laptop is getting hot often.

Issue with operating system

If after following each of the above recommendations your computer still continues to reboot it is likely that you are experiencing a Microsoft Windows operating system related issue that cannot be explained. To help make sure this is the case try the steps below.

1. Reboot the computer and enter CMOS setup as the computer is booting.
2. After you have loaded the computer in CMOS setup let the computer sit.

If the computer does not reboot while letting the computer sit in CMOS it is likely that you are in fact experiencing an issue with Microsoft Windows and it is recommend that if you have followed all of the above recommendations that you reinstall Microsoft Windows.

Why do Windows programs stop responding

 

 A computer, operating system, software program or driver may stop responding or cause other programs to stop responding because of several possible reasons, such as a confliction of software or hardware resources between two programs, lack of system resources, or a bug in the software or drivers.

To recover from a program that has stopped responding, press the Ctrl + Alt + Del keys on his or her keyboards to open the "Close Program" or "Task Manager" window, highlight the program, and click the "End Task" button to terminate the program. If another window opens, click the "End Task" button again to confirm stopping that program.

Note: It is important to realize that when a program stops responding any work that has not been saved will be lost when end tasking a program.

If you continue to experience programs locking the computer or stop responding we recommend you review our General Troubleshooting page for recommendations on steps that can be performed to help stop this issue from occurring.

Windows runtime errors

Before following the below recommendations for troubleshooting your runtime error if you're getting a runtime error with a runtime error code and error message such as "Runtime error 75 path/file access error", skip to the below runtime error listing for a listing of runtime error codes and additional information and causes for these errors.

Confliction with TSR or other running program

If you are encountering a runtime error message while in Windows or above ensure that the issue is not being caused by a third-party program or TSR by end tasking all open programs.

If, after end tasking all TSRs, you continue to experience the same issue and are running Windows 95 or Windows 98, verify that no utility or program is being loaded in the autoexec.bat and config.sys that is causing your issue by temporally renaming the files. To do this, follow the instructions below.

1. Boot to a MS-DOS prompt.
2. Once at the MS-DOS prompt, type:
   
   cd\ <press enter>
   ren autoexec.bat autoexec.ch <press enter>
   ren config.sys config.ch <press enter>
   
   Once completed, reboot the computer.

Software issue

If your issue persists it is possible that the program, utility or game causing the runtime error may have issues. Verify through the developer's website that all updates or patches that may be available have been downloaded and applied.

If no patches or updates are available, uninstall, and reinstall the program that is causing the issue. If you are having a runtime error in your operating system, reinstall the operating system.

Add-on, plug-in, or other extra software

Many runtime errors are also caused by other add-ons, plug-ins, or other extra software that has been installed onto the computer and is associated with the program generating the error. If you have any extra software installed that is associated with the program generating the error make sure there are no available updates for the programs and try uninstalling each of them to verify they're not the cause of your issue.

Computer virus

Because computer viruses are capable of tampering with the system settings or memory it is possible for a computer virus to generate a runtime error. If you are currently running a virus protection program on your computer ensure it has the latest updated patch or .dat file.

If you do not have a computer virus protection program it is recommended one be purchased or that a demo be temporarily downloaded to scan your computer hard drive for viruses.

• Additional information about computer viruses can be found on our virus information page.

Memory issue

Finally, if you have followed all of the above recommendations, it is possible that you may be encountering a hardware or memory related issue. We recommend that you first contact the developer of the program causing the issue for any possible solutions. If no solutions are found, we recommend you contact the computer or motherboard manufacturer for additional recommendations or service.

• Out of memory errors.
• Computer companies and contact information.

My computer is running slow what steps can I do to fix it?

Below are steps for Microsoft Windows users that should help speed up the computer or determine why the computer is running slow.

Reboot

If your computer has not been rebooted recently make sure to reboot it before following any of the steps below.

Background programs

One of the most common reasons for a slow computer are programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots.

Tip: To see what programs are running in the background and how much memory and CPU they are using open Task Manager.  If you are running Windows 7 or higher run Resmon to get a better understanding of how your computer is being used.

If you've got an antivirus scanner on the computer, spyware protection program, or other security utility make sure it's not scanning your computer in the background. If a scan is in progress it can decrease the overall performance of your computer.

Free hard drive space

Verify that there is at least 200-500MB of free hard drive space. This available space allows the computer to have room for the swap file to increase in size as well as room for temporary files.

• Determining available hard drive space.
• Regaining computer hard drive space.

Bad, corrupted or fragmented hard drive

• Run ScanDisk, chkdsk, or something equivalent to verify there is nothing physically wrong with the computer hard drive.
• Run Defrag to help ensure that data is arranged in the best possible order.
• User other software tools to test the hard drive for any errors by looking at the SMART of the drive.

Scan for malware

Today, spyware and other malware is a big cause of many computer problems including a slow computer. Even if an antivirus scanner is installed on the computer we recommend running a malware scan on the computer. Use the free version of Malwarebytes to scan your computer for malware.

Hardware conflicts

• Verify that the Device Manager has no conflicts. If any exist resolve these issues as they could be the cause of your problem.

Update Windows

• Make sure you have all the latest Windows updates installed in the computer.
• If you are on the Internet when your computer is slow also make sure all browser plugins are up-to-date.

Update your drivers

Make sure you've got the latest drivers for your computer, especially the latest video drivers. Having out-of-date drivers can cause an assortment of issues.

Memory upgrade

If you've had your computer for more than two years it's likely you're computer is not meeting the memory requirements for today. Today, we suggest a minimum of 1GB of memory (RAM) for 32-bit system and 2GB for a 64-bit system. By having enough memory for programs to run within memory your computer will not need to swap information stored within memory to the swap file. If your computer hard drive light is constantly active, its a good indication of your computer is swapping information betewen your memory and hard drive because of the lack of space in memory.

• Determining how much RAM is installed and available.
• What type of computer memory to use in a memory upgrade?

Hard drive upgrade

One of the biggest bottlenecks of a computer is the hard disk drive. For anyone with a slow computer or just looking for something to upgrade in the computer to improve overall system performance going from a traditional HDD to a Solid State Drive (SSD) will significantly improve the overall system performance.

Run registry cleaner

We normally do not recommend registry cleaners. However, if you have followed all of the above steps and your computer is still slow try running a registry cleaner on the computer.

Computer or processor is overheating

Make sure your computer and processor is not overheating. Excessive heat can cause a significant decrease in computer performance since most processors automatically step the speed of the processor down to help compensate for the heat related issues.

• What temperature should my processor be running at?

Dust, dirt, and hair can also constrict a proper air flow on your computer, which can also cause a computer to overheat. Make sure your computer case is clean and fans are not obstructed.

• Steps on cleaning your computer.

Erase computer and start over

If none of the above solutions resolve your issues, it is recommended that you either reinstall Windows or erase everything and then start over.

Old computer

If your computer is older than five years come to terms that it is likely the age of the computer that is causing it to be slow. Computers progress at an alarming rate as new programs and updates for programs come out their minimum requirements can increase and cause older computers to slow down. If your computer is older than five years we suggest purchasing a new computer or just realize after following the above steps it is going to run slower than a newer computer.

• How often should I buy a new computer?

Hardware issues

Finally, if your computer continues to be slower than normal after going over each of the above recommendations (including erasing and starting over) it's possible that your computer is experiencing a more serious hardware related issue such as a failing component in the computer. This could be a failing or bad hard drive, CPU, RAM, motherboard, or other component.

I have problems in Windows after installing new software

Reinstall or uninstall the program

\If you're encountering problems with your computer or other programs after installing new software on your computer, uninstall the program and see if the issues persist.

• Uninstalling Windows software.

Note: If after installing a program you're unable to boot into Windows, try booting into Safe Mode.

After the program has been uninstalled try installing the program again.

Check for software program updates or new versions

If you continue to experience issues verify that the program, game, or utility you're installing doesn't have any updates by visiting the developer of the program website.

If you're installing a software program or drivers for a hardware device such as a printer. Get the latest software and drivers from the manufacturer instead of using the included software. A listing of links to drivers can be found on our drivers page.

I keep seeing ‘There is a problem with this website’s security certificate’

Sometimes the biggest problems have the easiest fixes. According to support technicians, the lion’s share of issues are due to an incorrect system clock.

The problem is probably with your computer.

Website security certificates sync up with your computer’s clock. Old computers in particular run the risk of having a dead CMOS battery—the watch battery in your computer that keeps its system clock ticking. Click the clock in the system tray and select Change date and time settings to correct any issues.

My Wi-Fi keeps disconnecting

Spotty wireless connections can be a puzzler. Is it your computer? Your router? Your ISP? Try a few things before calling your Internet service provider.

Windows Network Diagnostics may not always solve your problem, but it will usually point you in the right direction.

Confirm that your computer is within range of your wireless router. Weak signals mean weak connections. Next, make sure your PC’s wireless card has the latest drivers. Try letting Windows troubleshoot for you by right-clicking the Wi-Fi icon in the taskbar and selecting Troubleshoot problems.

Pop-up ads are appearing on my desktop

If you’re not running your Web browser and are still getting pop-up ads on your desktop, you’ve most likely installed adware—a program that displays unwanted ads. Although benevolent adware exists, most of the time adware is up to no good. Getting rid of it isn't easy. “There’s a ton of little system-utility tools out there that promise to clean up everything, with names like PC Speed-up, PC Speed Pro, PC Speedifier,” Geek Squad’s Meister says. “A lot of times those programs are not going to do much. Some programs will work, others are snake oil.”

Avoid downloading programs that offer to speed up your PC or clean up your registry. Instead, use a trustworthy adware scanner like the free version of Malwarebytes' Anti-Malware tool.

Running a full scan with credible antivirus software is your first step. If that program doesn’t find and remove the adware, turn to Malwarebytes Anti-Malware Free, a great utility for removing all types of malware. Just make sure to disable your standard antivirus software before running it.
“Multiple antivirus programs working at the same time will often result in problems,” Falcon Northwest’s Petrie says. “You only want one active, real-time antivirus scanner installed, but it doesn’t hurt to run an additional ‘on demand’ virus or malware scanner.”
Searching online for the name of the advertised product can sometimes yield solutions from fellow victims. If all else fails, there’s always the nuclear option: a complete system reinstall. It might take a long time, but it’s the only surefire way to remove adware or spyware. Remember to back up all your personal files.

My Computer Keeps restarting

Hardware problems are hard to diagnose and solve. First, confirm that you aren’t just getting the latest wave of Windows updates, which can automatically restart your computer during installation. Then work on updating all of your critical system drivers. Your graphics card, motherboard, and network card drivers are crucial.
“Sometimes it can be viruses, sometimes it can be adware, sometimes it can be overheating, and sometimes it can be something as simple as making sure your video card is updated,” Geek Squad’s Meister says.
Is your computer making weird noises? If you’re lucky all you’ll need to do is give the machine a thorough cleaning. Modern computers have safeguards that shut down the system if a component is overheating, which can be the cause of frequent restarts when you’re running resource-intensive programs or video games.

My computer is too slow

The first step to fixing a slow computer is to verify that your machine is the actual source of the problem. Videos that seem to buffer forever, and websites that take ages to load, may not be your computer’s fault. Geek Squad agent Derek Meister claims that many people mistakenly identify a slow system as the problem when “it’s actually not the computer, [but] their broadband connection.” See “Downloads are taking forever” below for instructions on how to use Speedtest.net to diagnose a slow connection.
If the problem is your PC, check whether you have plenty of free space on the hard drive holding your operating system. Windows needs room to create files while your system is running. If your hard drive is maxed out, performance suffers. Now is the perfect time to clear some space.

If your computer’s operating system resides on an overstuffed C: drive, clearing out some space could boost OS performance.

Microsoft’s System Configuration tool is your next-best bet for tackling slow performance. Many applications launch automatically when your machine boots up, which can stretch out boot time—especially on older, slower PCs. Make a habit of trimming the startup items. Open the tool by pressing Windows-R, typing msconfig, and pressing the Enter key.
Checking the Startup Item and Manufacturer columns is the best way to figure out which potential performance-killers you can safely disable. Avoid messing with any of the services and programs that have Microsoft Corporation listed as the manufacturer. Items such as AdobeAAMUpdater, Google Update, Pando Media Booster, Spotify, and Steam Client Bootstrapper are all fair game. Regardless, err on the side of caution: If you’re not sure what the program or service does, don’t disable it.

Windows’ System Configuration Tool lets you disable programs and services that automatically start when you boot your computer.

Once you’ve made all your changes, click OK and restart the computer. It should boot up quicker and feel noticeably faster.

If you boot up, and the computer cannot find the C: drive, you might have a bad hard drive.

If you boot up, and the computer cannot find the C: drive, you might have a bad hard drive.
 If you have another computer, swap hard drives to diagnose the problem. If your computer boots with the other drive, yours is probably bad. Sometimes, a reboot will work. Your drive might have enough life to spin up occasionally. If this works, transfer your data to another drive, pronto. According to techie lore, you can seal a nonworking drive in a bag and put it in a freezer overnight. That could shrink things enough to free them up. I've used this trick a few times and it's worth a try. A regular backup regimen will save you in case of hard-drive failure, assuming you aren't backing up to the same hard drive. If the drive is dead and you don't have a backup, a computer shop may be able to save your data. Hard drives are cheap. You can get a replacement for less than $100. Get one boxed for retail, which will include instructions and any hardware needed. Your hard drive is in the front of your machine. It will be about the size of a paperback book and is probably held in by four screws, two on each side. Power and ribbon cables connect to the back. Put the new drive in and install it as the master. Reconfigure the old drive as the slave. The instructions that come with the new drive should explain that. Boot the computer and install Windows on the new drive. If you're lucky, the computer will see the old drive (it will be D:). You can then transfer your data to the new drive. Replacing a hard drive is more difficult than the other operations. However, if you pay to have the work done, it may not be cost effective. You might be better off buying a new machine. So if you are adventuresome, and you have the time, changing the hard drive may be worthwhile.

If you regularly get the "Blue Screen of Death," you may have a random access memory (RAM) problem.

If you regularly get the "Blue Screen of Death," you may have a random access memory (RAM) problem. 
Note the message on the blue screen, especially the numbers. Check it in Microsoft's Support Site. Also, put the text of the error message in a search engine and check the Internet. Assuming you can diagnose it, a memory problem is easy to fix. If you can't find the diagnosis information you need online, you can try swapping out memory sticks from another computer. But that memory must be the same type. If all else fails, take the old memory to a computer store. The people there may be willing to test it. Sticks of memory go in slots near the microprocessor. They're about four inches long. Remove the old memory and match it at the store. Memory prices are all over the map, depending on type and speed. Be sure you get the same type. When you press the new memory into the slot, you will probably have to use some force. The clips on each end will snap into place when the memory is seated properly.

The computer comes on, but nothing appears on your monitor.

In other words, Windows never shows up. You may have a monitor problem. Try using another monitor you know is good on the computer and see if anything shows up on the screen. If the second monitor works, the first one is bad. Monitors are not worth repairing. Just buy a new one. Never open the back of a monitor to fix it. The capacitors inside monitors store electricity. You could be injured or even killed. If the screen is dark, it could be a video card problem. First, find the video card. This is a circuit board that fits into a slot in the motherboard. The cable from the monitor connects to the VGA (video graphics adapter) port, which sticks out through the back of the computer. If the VGA port is part of the motherboard, the video is built in. You can't fix that. Otherwise, it will be part of the video card. Assuming you have a separate card, be sure it is firmly seated. The front end of the card can rise out of the slot inadvertently when the back end is screwed down to the computer frame. If you have a computer that is working perfectly, turn it off and remove the video card. Put the card that works in the problem computer. If the system works, you need a new card. If you don't have an extra card to test your system, buy a cheap one ($30-50). If it doesn't solve the problem, take it back. You can spend hundreds of dollars on a video card. But if you're running business applications and surfing the Web, buy on price. The expensive stuff is for serious gamers.

You turn on the computer and nothing happens

No lights, no beeps, no fan noise. What is the first thing you do? Be sure the darn thing is plugged in!Even if you're absolutely certain that it is connected, double check. Assuming that it is plugged in, you probably have a bad power supply. This is a metal box located in the top and back of the computer. It is usually held in by four screws and the power cable connects to it. A fan blows air out the back. A wiring harness exits the power supply inside the computer. Numerous power connectors are attached to the ends of the wires. These plug into drives, fans, and possibly other gizmos. The harness also will have connectors to the motherboard. It doesn't matter which wire connects where, as long as the connector fits. When you open the computer, this mess of wiring can be very intimidating. Study it, and you'll find it less mysterious. Note the connections in writing, if necessary. Disconnect the wires and remove the power supply. Take it to the computer store and get a replacement with the same wattage. Figure on spending $50-70.

Login problem on Windows xp due to mscd.exe

Login problem on Windows xp due to mscd.exe

Problem:

Recently we received a mail from one of our readers having some login issues with windows xp due to a file named mscd.exe ,so when ever he tries to login an error message pops up saying “error loading mscd.exe”

So what is mscd.exe ?
mscd.exe is basically a spyware or adware which infects your system in the following fashion:

• Installs programs.
• Deletes programs.
• Registers Browser Help Objects.
• Creates Run Once Keys.
• Runs other programs.
• Creates known malware.
• Creates copies of itself.

Solution:
If you are able to login into your PC, update your anti-virus definitions and then run a full virus scan on your PC. This may help fix the problem. But if this does not help, then back up all your important data on some DVD or any other external device. Format your system completely and re-install Windows on your machine.
Tip: To avoid so much inconvenience make sure you install proper anti-virus software and keep it updated regularly.
