I have had three computer-related disasters just this last week. Any help would be appreciated, even such advice as to cut my losses and buy a new computer.

When I press F10, it changes to "Entering Setup" and then nothing else happens no matter what I do. I've already tried putting in the Windows XP CD that came with the machine, but still nothing. Nothing happens with this computer no...
