Have an Asus Rampage Extreme. Was running good for about 2 months then all of a sudden I lost power. Thought maybe it was the power supply. Put a new 950W PSU in. Started up for about 10 minutes then died. Waited an hour and started again. This time it went down after running for 3 minutes. This system has never, ever been overclocked. I have run on all default settings since installed. Felt components and nothing is hot and all are just barely warm. Have no clue which way to go now.
