well is there any possibilities that this problems is caused by any 'bad' or 'infected' files or something? because it is not like all games which is uses graphic card are cannot be played. for example, i still can play SRS, Counter Strike, Midtown Madness 2 and NFS Hot Pursuit 2. But games from Rockstar and EA Games are cannot be played..like GTA SA, Midnight Club, NFS Carbon, NFS Underground and Test Drive Unlimited.
FYI, my pc is Windows Vista Ultimate with ATI Radeon 3200 Graphics, and uses AMD Turion X2. i also already updated my antivirus and scan the whole computer, but still...this stupid problem exist.
Aww man i'm twisted!!!
