I'd recently clean installed windows 7 64-bit on my 1 year old system. Everythings' great except for gaming. I tried running COD4 which is suppose to play nice with 7 according to Microsoft but it just couldn't last more than 5 minutes on single player mode. It just keeps crashing. I haven't tried multiplayer as I knew you have to apply a patch before able to run punkbusters. Anyway, I'd uninstalled the game and install it with all the lastest patches (up to 1.7). But still it crashes. Every time the crash is a nasty one, meaning I can't use Contro+Alt+Del go back to the desktop but have to hard reset the machine. I'd tried running Prototype as well, it lasted a bit longer but still hard crashes. All of my graphic drivers
and BIOS were up to date and I still can't think of any reasons for the crash. I'd even turn off overclocking and run it on stock speed. As a note, all those games plus many others were running great on the same system with Vista Ultimate x64. Any logical solutions would be much appreciated.
