Computer randomly restarts?

Question

My computer randomly restarts itself from time to time. At first i thought my liquid cooling system was going bad so i put in fans for my cpu and it has been running from about 30-42 degrees celius. Could it be a hard drive issue from all the times it use to restart? sometimes when it restarts it wont show the bios. but if i leave it go for about 4hrs it will boot just fine..
i need help and i dont feel like buying parts with out nowing for sure

Answer 2

It may be a fatal error that is causing the computer to restart. You can easily stop the restart problem by changing your system

features to restrict automatic startup when your computer's having a problem. Here is how:

You should look at youe PSU. If a PSU overheats it will also force a reboot. You might have to get a new PSU, since it sounds like you could be running alot of devices off of it.



A higher wattage PSU, with decent cooling might solve your problem. If you can, also check to get certified PSU's. Your hardware performs a bit better with PSU that they were designed for.

Answer 4

I think that it still the problem with cooling, as after hours all became fine.

When is the problem with cooling you can run the computer for few minutes to 15 minutes, and then it reboots and still rebooting in intervalls of minutes.

Answer 5

just re-install your operating system and it will be all right. check whether your restart key in your cabinet or keyboard is stuck
