I recently purchased new parts for an upgrade to my current machine. I got everything setup and built last Friday and the computer ran like a dream over the weekend. I woke up on Monday morning to find that while the case light were on the computer itself was off (although the fans were running). I powered down the computer, waited and tried to turn it back on but it would not respond. After several attempts I managed to get the BIOS splash screen and it stated that the BIOS had become corrupted and was being fixed. That finished and the computer rebooted back to the BIOS splash and then booted windows. I got into windows for about ten minutes and the computer seemed to shutdown again ( no video, no keyboard/mouse) but the lights on the case and the fans are still running. I have tried clearing the CMOS by removing the mobo battery but the problem still persists. Now the machine will only POST if I let it sit there for about two hours and then cold boot. Then it will boot and load windows only to cut off again randomly, normally within 3-5 min. The only software that is loaded on this computer was the OS, MS Office 2K10, and DCS - A10C.
I know that there is a BIOS update for the mobo, but with the random occurances of the computer shutting off I think that it would be VERY risky to try to update the BIOS.
Please HELP!!!!
