I have an Asus A8R32-MVP deluxe motherboard with an AMD Athlon X2 64 Dual core processor 4200+ and 2 GB DDR SDRAM. All this is powered from a Corsair 450W PSU. I recently installed Windows 7 Pro on it which worked like a charm, but this morning when I logged on it was stuck loading on the Welcome screen and then crashed with a bluescreen that flashed for about a half second before dying. I tried booting again but it got stuck at the BIOS screen where it was trying to detect the Third IDE Master, where it seemed to freeze. I powered it off completely and tried to start it again, but it kept getting stuck there. I switched the SATA plug that the hard drive was connected to to no avail. I then cleared the CMOS, but when I went to turn it on it would remain a black screen and never even get to the BIOS POST screen. The CPU fan shut off a few seconds after first powering it on and would not start again. I have tried to reclear the CMOS but to no avail. Help?
