Does anyone have any idea what the problem could be? My guess is that i have some fucked hardware but don't have any idea what it could be.
If your computer is randomly restarting it can be due to a number of reasons.

1) The first thing I would do would be to check the CPU temperature in the bios. 55c+ is usually when you should begin to worry with your processor. If it's too high, you can try blowing the dust out, and if that doesn't help you should reseat the heatsink or get better airflow in your case. An overheating processor will cause your computer to randomly restart or freeze once it reaches a certain point.

2) The next thing I would check is the RAM. A few months ago my friend added some new RAM in his computer, but it conflicted with the RAM he already had and was causing data to corrupt, thus freezing and restarting his computer at random. There is a program called Memtest 86 that you can make a bootable floppy with and test your RAM. If it fails any of the tests then your RAM is bad. And yes, it can just stop working properly "just like that."

3) Run virus/spyware check and clear anything it finds out.

4) Check all the hardware in your computer and make sure everything is connected properly.

5) Re-format and reinstall your OS if all else fails. Once you reinstall the OS, if the problem still continues, then the problem is obviously with some piece of hardware.

There are tons of other reasons related to the OS that could cause it to restart, but I usually don't take the time to check for things like that. In the case that something is wrong with your OS, you should probably just reformat, anyway.

Have you added any new hardware recently?
