Hi guys I have a problem regarding my PC. Once every 3 minutes, my PC display freezes for about 15 seconds then resumes to work normally. The interesting thing is that during these 15 seconds only my display freezes while everything else works normally. For example if I am playing a Shooter Game and my display freezes, I am still able to shoot guns and move my character during this freeze, but the screen is simply frozen. Here are my computer specifications: Processor: 2.33 ghz Q8200 Core 2 Quad Ram: 4Gb DDR 2 Video card: Nvidia xfx 9600 512 mb 256 bit Supply: 350 Watt Hard Disk: 350 GB OS: Window Vista Ultimate 64 bit If you have any information to help me fix this issue, please share. Thanks Additional Details Already updated with the latest drivers, and recently formatted and reinstalled windows.
