I've had a stable running home built system for about 10 months now. Just recently, I began having problems with my CD drives (they would be unavailable in XP). Then tonight, while I was rebooting my system to get the CD's working, I powered it off and it will not even enter POST. Pressing the power does nothing. I checked the switch and it is closing properly. I disconected all drives and still nothing. The green light on the Asus A8n-SLI Premium is on solid and the PS seems to me working, though I dont have an official way to check it. Any suggestions before I strip it down and bench check it?
