I'm guessing a rootkit of some kind. Regular anti virus won't help. Try the Microsoft Safety Scanner: http://www.microsoft.com/security/scanner/en-us/default.aspx

You'll download an .ISO you need to burn to a CD, boot with that and scan that PC.

First check the integrity of your RAM with memtest86+


Happened to me once - PC stopped loading at desktop, nothing further. SO I reinstalled Winders. Bombed out. Only then did I think of testing the RAM - and it was definitely faulty. So I replaced it, and the PC's working fine for now.

You can try running a repair install - Google for instructions

I +1 the recommendation for checking your RAM. You will be wasting your time doing a repair if the ram is faulty. Most likely you will just make things worse.

So check the RAM first thing!
