hows your bios I am interested to see if others with more experience have to say about programs like Bios Wizard which was free at Major Geeks a while ago and tells you if your bios is functioning correctly
try replacing the busted drive with one you know works. if the replacement works, the old drive is broke. it the new one doesn't work, you will have to look elsewhere...like at the drive controller/cable/mobo/windows.
