I've had several BSOD since a clean install of my Windows 7 (64 bit). Did a clean install of all my drivers, updated my bios etc. Performed a hardware test using Burnintest with no errors. BSOD usually occur when playing games such as Guild Wars 2, DOTA 2, and Minecraft. Motherboard: Asus M3N78 Pro CPU: AMD Phenom 9950 Quad Core 2.6 GHZ Memory: 8GB DDR2 Video Card: Nvidia 9800 GTX Included the dump files and such. Please let me know if you need anymore information.
