Trouble:

We have received lot many problems from our readers complaining that their computer restarts abruptly. It seems like that the computer restarts without any reason, but it is not so, every-time your computer restarts abruptly, there must be some or other reason that you might not have noticed.

In this post we will look into those reasons and the possible solutions to fix computer restart problem. So lets have a look at the possible reasons:

• Computer restart due to overheating
• Computer restart due to faulty RAM
• Computer restart due to faulty Hard-disk
• Computer restart due to overheating up of hard-disk
• Computer restart on attaching some external USB device
• Computer restart due to other hardware problem
• Some software causing operating system crash causes computer restart

There may be some rare typical reasons also, but let us focus on these common reasons and lets have a look on how to fix computer restart problem because of above reasons.

Going one by one, lets see how these problems can be fixed:

Computer restart due to overheating:

Computer restarts due to over-heating when the processor fan goes faulty. See this post for detailed solution.

Computer restart due to faulty RAM:

Computer restarts abruptly if RAM goes faulty, or if you install some in-compatible RAM or more than one RAM modules of different frequency or type. See the RAM upgrade post for details.

Computer restart due to faulty Hard-disk:

Faulty hard disk is one of the most common reasons for abrupt computer restart. Run a hard disk scan to fix this issue. If there are bad-sectors on your hard-disk, its the time to get it replaced.

Computer restart due to overheating up of hard-disk:

If there is not proper ventilation around your computer, the hard disk may also reach temperatures where it starts to malfunction and computer restarts in some of these cases. The fix is to keep the computer at a ventilated place. Also installing some cabinet fans also solves this problem to big extent.

Computer restart on attaching some external USB device:

I have experienced that when I attached my memory-card-reader to my computer, the computer restarted. I tried it again, it again re-started, it was not a co-incidence, it was a faulty device. So the fix is, remove all external USB devices and insert one by one, and see which device is causing problem.

Computer restart due to other hardware problem:

Computer restart problem is also caused by faulty motherboard sometimes,for example my desktop’s BIOS went corrupt a few weeks back. But the chances of motherboard are relatively low, so if nothing else seems to help, get the motherboard checked by hardware vendor or technician.

Some software causing operating system crash causes computer restart:

Sometimes a software can also be the culprit behind the computer restart. If you have recently installed any new application or game, and computer has started to restart when using that application or game, you need to un-install it to fix the issue.
