I have Windows 7 64-bit with all the latest updates. I have a Gigabyte Z77-D3H motherboard, 8GB of DDR3 RAM, intel i5 2500k CPU, EVGA Geforce GTX 570 videocard My video drivers are up to date, all drivers are up to date. I get a blue screen randomly and the computer reboots. Here's the log from Windows: Anyone have any idea? I ran memtest86 and no problems. THis is from WhoCrashed. Does anyone know what this means? Or can point out a section of this forum or another forum that has people who know? I'm getting desperate.
