i have a prblem and please help me identify what is the problem.
while i open games like cabal online, warcraft III, or even 3d live pool, also when watching video, browsing pictures, and worst is even when i'm just browsing the net.,
my screen flash and the graphics will be scattered, then flash again and: 1) it will come back to normal. 2) it will hang up. 3) computer will restart.

i tried changing my video card but the problem still occur, i also try other RAM but it doesn't make any changes..

what might be its problem ??


Have you run any anti-malware programs? I suggest you run a scan to make sure your machine isn't infected.

Have you tried a different monitor?
Does this problem happen before logging in and does it happen if you don't do anything(log in and just leave it)?.
