Compaq hard drive help

That's pretty much like saying "I was walking along the street file until I got shot in the head".

Buy a new hard-drive, install a new setup of Windows on that (using restore disks or whatever came with your PC). Plug in the original drive in as a secondary disk, or get an external USB enclosure for it, and copy over your My Documents, Favorites and Desktkop directories from your user profile in C:\Documents and Settings\username (if you have XP).
