Just built a new computer... ASUS m3n72-D mobo AMD 9950 2.6 Quad Core 4 GB Corsair RAIM EVGA GTX 260 graphics card NZXT Ultimate Cooling Chassis Took a 120 GB harddrive out of my old computer (a gateway) It ran like a champ for approximately 2 weeks. Now it will not power up at all when I press the power button. When I unplug the PSU or flip the off switch on the PSU, and then plug it back it, the computer immediately begins to try to power up (without me even pressing the power button!). It will begin to power up for about 5 seconds (lights up, CPU fan starts, case fans start, monitor lights up, etc) but then will immediately shut itself off. At first I thought it might be the power button/cord on the chassis, and I fiddled with the connections on that, and then I pressed the power button and it began to start. Again however, it shut itself down after a couple seconds. After the first time messing with the power button connection, the power button will not do anything ever. The computer still attempts to start itself after being unplugged and plugged back in, but always dies.
