About two months ago my computer started freezing, then rebooting when I
tried to play a game. It never did this before two months ago, and happens a
few minutes into the game. I have tried to play CounterStrike:Source and
Warcraft 3, both of which have very good graphics. Sometimes the computer
freezes and the screen turns black, then it reboots, while other times the
screen turns blue, and sometimes there are error messages on this blue
screen. Every time I send an error report to Microsoft it says it is caused
by a "device driver." I have updated, rolled back, and deleted and
reinstalled all my drivers, but it is probably the display driver. I have
defragmented my computer, scanned for viruses, and gotten the latest software
updates. Is there any way to fix this problem without replacing parts of my
computer?
