Need help badly, computer dying!!!!

My roomates downloaded a bunch of stuff, and now my computer is worthless!

First off, my computer now shuts off and restarts at random. Also, i can't load Internet Explorer without it going to: c:\winnt\secure.html then it shoots up more pop up porn sites.

Also, an Active Desktop keeps coming active on my desktop with a giant ad for my background. Here is my HijackThis! record, i tried removing stuff but it all comes back. Also, I've run AdAware and it didn't help either, everything comes back.... Please help as i no longer have my Win2k disc, and i have no way of getting my OS back if i reformat, and plus i have a ton of pictures and stuff i don't wanna lose. Any help would be greatly appreciated.

Oh and now my computer randomly locks up completely too. System idle starts using up 100% resources. I'll see if i can even get my HijackThis report.
