As much as I would love to do all of those things... the computer with the problem will not boot up! Even when I try to boot it into safe mode it crashes and gives me the BLUE SCREEN OF DEATH

Right now I am on my husband's laptop because the only thing that I can do with MY doorstop of a computer is to run a bootable disc. I was able to run memtest because it was on a Linux CD. The Windows Repair Console was about as helpful as a bottle of water for a forest fire. It crashed as well
