My PC reboots

[Voodoo]

When I play any game, it reboots. The lower the graphics, the longer the game, but it still reboots. Help.

Do you see any warning before reboot? Blue-screen maybe?
Check CPU temperature... Maybe it getts up to some amount in which computer restarts...

Also, maybe try to format your HDD and reinstall windows... You didn't give many info about your computer....

Yea, I get a blue screen.
Here's all what I can post shortly.
And I had this once, formating and reinstalling wasn't needed, but I forgot what it was then.

[FlameMan]

well, then it depends of what does the blue screen say.... it can be every single driver causing that.. :P
can be wrongly installed Graphic driver ;P

Ah well, I can't read a whole page in less than 1 second. I suspect its a virus, cause it randomly happened.

blue screen (called death screen also) can be sign of some computer parts broken.. like graphic card, CPU, motherboard, RAM Memory, HDD... but it also can be sign of virus or wrongly installed drivers... i would suggest you to pull out internet cable, format your computer, install PROPER drivers, install some anti-virus program with good viruses database and i hope it will fix it..

if not it means that its problem with parts
