I have a htpc I built, i5-2500k with asus p8p67-m pro and gskill ripjaw ddr3 4x2 and 2x2 ram. I had it in another build before and it started crashing, so I did a new build and replaced everything, hdd, psu, new version of windows, and same problem. It freezes after being idle for hours, like this time it froze about 6 hours later. I have sleep turned off and hibernate off. Can anyone help me with some troubleshooting.
