restarting computer problem help?

If you're overclocking, that can cause heat issues.

If you can, enter your BIOS setup, let it sit there for a while, and give us a CPU Temp reading.

i thought i just said i figured out what was wrong? all i wanted to know now is can anything bad or something happen to your computer when you restart like in a middle of a game?, wow, you dont always need computer specs just to help someone on their computer

Yes you do... since all you have said is it restarts for no reason. You haven't even told us what Windows version you're running. There are a million things that could restart your pc. You can get disk errors on your harddrive, I'm not exactly sure, but it's not healthy for it.
