I just purchased an M2N-E mobo. After I got everything up and running I installed the current game I am playing Dark Age of Camelot. After a couple times of ALT+Tabing to mess with media player or look something up on the net the computer restarts itself. This also sometimes happens when I log out of the game. Other than this the system run great. I have tried every bios update, every chip set update, the latest video drivers, and clocking the memory down to PC-5400. I am at my wits end with this thing Please Help. I have manually set the RAM timing to 5-5-5-12 and the voltage I have tried are 1.9v (Rated memory voltage) and 1.95 (this is as high as the mobo will go sadly).
