Can't run any games properly on Win 7 Ult x64

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.

You might check to make sure you have directx 9 installed, and that you have the old c++ libraries. In my install of Win7 those were missing and a lot of games wouldn't work because of it. Otherwise it sounds like a driver error but you say you're all up to date, so that's all i can think of.

if you still have issues, you may have to try different versions of your graphics drivers.

Well it couldn't be that your diretx is out of date since directx 11 comes with windows 7. What I would suggest is first making sure your video cards are compatible with Windows 7. Check the manufacturer's site. Try uninstalling and then reinstalling your drivers. Also, this might be that the windows 7 install didn't work correct and now its erroring out.

no, its not that its out of date per se, its just that he may not have the directx 9 runtime or whatever. afaik, it doesnt come by default in the win7 install, you just get dx11.

yes this is correct , I play a game called Entropia Universe and there are two things I have to update in windows 7 before it will run, the first is the 33.5 MB install of direct x 9.0 and the second is the 32bit version of visual c vcredist_x86.exe , this is because the installer and runtime are still 32 bit and codings not great, even though the game engine is crysis
