I have an interesting situation.

My computer will boot to the windows XP splash screen (were you see the
Windows XP logo and the rainbow bar on the bottom, which is moving) and
then the screen goes black and after about 3 minutes, the computer
displays a primary hard disk not found error.

Weird because if the Primary Hard Disk hadnt been found to begin with,
the splash screen wouldnt show. The computer also wont boot in safe
mode (does the same thing) and wont boot with 'Last known good hardware
configuration".

Any ideas?
