So last night I get home to find my computer sitting on a screen that says that the windows kernel is corrupt. So, I load up the windows disc, but now I can't POST. I turn off the psu, and I can POST, but I get a "bad BIOS checksum" message. I put in the motherboard cd to restore it, and it reads it as the manual says it should, then tells me to restart. Except when I restart, I get the same error. Help.
