Hello, I have a fresh install of Windows 7 Ultimate x64, but I had this problem before. Basically, after 20-30 minutes of playing, I get BSOD (minidump attached). Specs: MB: ASUS P5K SE/EPU CPU: Intel Core 2 Quad Q6600@ 2.40GHz RAM: 6 Gb (2x A-data 2Gb and 2x Kingston 1Gb) PSU: Corsair 650W (Don't remember the model, if asked, I will find out) GPU: MSI 560Ti HAWX The only new thing in my PC is the GPU, all other hardware is at least 5 years old. Can you help me? Thank you in advance.
