So I built the PC in July and, despite an issue with the GPU (not the integrated one), it ran perfectly until just today. I left it on while I went and played a game elsewhere, and returned to see that it had shut itself down. Pushing the power button has no effect, except that I hear a tiny little noise somewhere in there. The motherboard seems to be receiving power because the lights that show the manual reset and power buttons are still lit. They're not working though. Any ideas about where I should start?
Intel i7 2600k Asus P8Z68-V Pro motherboard OCZ Elitexstream 1000W power supply EVGA Geforce GTX 570HD GPU WD 2TB HD WD2002FAEX and if I'm not mistaken... Kingston KHX1600C9D3K2/8GX (2x4GB)
Power is plugged into a UPS: Tripplite Omnivs 1000VA It seems to be working for anything else that plugs into it.
