I built a new rig one week ago. It worked fantastic since then,. Shut it down last night after it appeared to go into sleep mode, but I couldn't get out of it and just manually shut down. This morning I wake up, push "power" and nothing. No response whatsoever. No fans, no recognition at all by the machine. The green LED light on the mobo is on. I have an Ultra PSU and thought perhaps it was the culprit. Bought a Corsair, installed it, and again nothing when I press power. Reinstalled the Ultra, again no response at all. Completely at a loss. Processor: Phenom 2 965 RAM: 4 GB GPU: 5870 Mobo: Asus M4A79XTD Evo PSU: Ultra 650w LS Haven't even touched any overclocking. I beg you, please help.
