I have a new PC (5 days old) that will crash to the blue screen if I leave it alone for several hours. It does not crash under heavy gaming use or just surfing (go figure). No overclocking. CPU is I7-3820, memory -Corsair Dominator 16gb 1866, drive is the OCZ Revo Drive Hybrid (PCI express model), Power supply is Corsair gold AX850, cooling is Corsair H100, video is EVGA GTX 560TI (no blurring issues per the other post), and a Corsair 650D case.
Left the PC on all night and this morning I could not wake it up so presumed it crashed again (monitor was dark). Did a hard shut down and turned back on. It failed the bios part and restarted itself several times failing each time until it gave me a multiple error message saying that either I had power issues or overclocking issues. It offered me the option to set everythign to default levels. I did and it rebooted.
Memory was reset to the 13333 level .... I set it back. It rebooted fine as well. I know it will crash again after several hours of doing nothing.
Any ideas on what I should do or what the source of this problem may be? HELP please.
