Well there it basically is. I just bought Dirt 3 and Hitman absolution but unlike previous games such as Far cry 3 and COD Blacops 2 they totally freezes my computer just few seconds after double clicking the game exe or pressing play from the autorun. Nothing works after that its just like screencap of my desktop with absolutely no mouse or keyboard control. i have Windows 7 ultimate 64 bit. intel core quad q6600 2.4. 8gb RAM, ATI radeon HD4800 series and 850 w nexus power. i have all the latest drivers and updates to everything .
