Here is my suggestion:

Download malwarebytes antimalware. (Free)
Download Microsoft Security Essentials (Free as long as your copy of windows is legit)

Update both as soon as they are installed, and then run one after the other. Do full scans instead of quick scans.

If either of them turn up with a message saying you need to reboot to finish cleaning, REBOOT IMMEDIATELY.

Scan both again.

If you continue to get the same messages about the same files over and over again, consider downloading and burning to a disc the AVG Rescue CD.

You can turn your computer off and boot your computer using the CD. This disables your hard drive and allows the cd to scan the hard drive for viruses without them being able to keep your system from deleting them.

If you need any more assistance feel free to pm me.

I have my BS in Computer Science

It died during the reformat? Did you boot into the cd or did you boot into your hard drive and use some option once your logged into windows? You need to boot to cd. If it still is turning off you are dealing with overheating, or a loose cpu fan.

When it turns off, can you immediately turn it back on?
