Dont know if its been posted before but when i start a game my computer restarts for no reson sometimes i can see a Blue Screen of Death before the restart i was wondering how to fix this

sys spec

32MB vid card (ati) - yes i did try the ATI fix button
265 Ram
800MB processor
Sound Blaster

I got that with my old computer, too... Change the sound settings the setup, like, what driver it uses or whatever... I managed to get it to work by doing that.

I don't know which OS you're using, but in Windows 2000 you can disable the automatic reboot after a bluescreen, so you can check what the bluescreen says:
Press Windows Key + Pause > Advanced > Start & Recovery (dont know the exact name, it's the third button) > System Error (lower box) > Disable "Automatic reboot"

From now on, everytime your computer bluescreens you can check what the error is. Just remember the error message/what file failed.
Well, before you do that, try what Lazehboi said.

ah thank b00sta i seen what the blue screen said and it was something with the video, so i updated my video drivers and it works =D, thanks for the help
