PROBLEM: The game freezes mid game when playing SP or MP. When the screen freezes the colors change to random ones or in the case of CoD4 the colors change before the freeze happens but lets me play for a minute or two before it completely freezes. In CoD4 the game also says that iw3mp.exe isn't responding when this happens. The Games: CoD4 Left 4 Dead The System: To the right of my user name. Drivers: Realtek Ethernet and HD Audio drivers (downloaded from the gigabyte [my motherboards] website) 195.62 GTX 280 Driver (most recent) These games worked fine when gaming on Vista Ultimate 64-bit. The only variables changed besides the windows version is the Realtek drivers. I originally used the CD that came with the motherboard and downloaded the drivers from there. Since I now have Windows 7 I decided to go directly to the site and download the drivers. Possible Fixes: Install the newest Realtek drivers directly from the Realtek website. I would love to fix this ASAP because I usually game every day. Any help would be greatly appreciated. EDIT: Game Settings: Every setting is on high and the resolution is 1680x1050 Other: My GPU IS NOT overheating, nor is the CPU. The GPU is not OC'd as of now but the CPU is to 4.0GHz.
