A little background first. About four weeks ago I purchased a custom computer off e-bay. This build is centered on an ASUS P5kPL-CM motherboard with an Intel e8400 Core 2 Duo and Nvidia 8600GT graphics. Has 4 gigs of Kingston RAM installed and Running Vista 64 Basic.
This Build ran fine right out of the Box. Then yesterday it died on me and I don't know what went wrong. The last thing I did before it died was activate Windows which was giving me a 3 day warning. After the activation was successful I walked away from the computer for a few hours and when I came back it was dead. Screen was black, keyboard and mouse had no lights and were unresponsive. The case and cpu fans were running but nothing was going to the monitor. It was like it was stuck in sleep mode and would not power down either. I had to switch off the surge protector to get it to restart.
When I powered the system back on the motherboard will no longer POST. Everything powers up: Case Fans, Lights, CPU fan, Hard drive, DVD-R, Video Card fan but nothing displays on the monitor. Even the LED on the motherboard will light up but it makes no warning beeps or POST errors. Screen is black with no way to get into BIOS. Not sure what is wrong or how to trouble shoot this.
Any help or suggestions would be appreciated. Thanks in advance.
