Where does it fail? Does it fail during the repair, or after it when you try to boot up Windows? At this point, everything should still be intact on your hard drive and accessible.
The SPAM report from your ISP suggests, to me, that you may have become a "zombie" for some spammer (who accessed your system and caused it to send out spam!). And, that depends on how they accessed your system and router.
I'd say that a low-level reformat and clean install of Windows is your best bet right now. A low-level format can be done with free tools from the hard drive manufacturer's website, and a clean install will allow you to start out virus free! Don't forget that you'll have to update your motherboard and system hardware drivers after the clean install (along with the obligatory visit to Windows Update).
Here's a couple of suggestions to keep this from happening again.
1) Anti-virus software - updated daily and used always!
2) Anti-spyware software - updated daily and used always!
3) A software firewall - used always, updated as needed!
4) Windows Update - go there daily to check for the latest updates - then download and install them!e
5) Watch where you surf!
6) Don't ever click on anything that you didn't ask for. Close it (or it's application) by using Ctrl-Alt-Del to open Task Manager and close the application that it's running in (usually Internet Explorer).
Some tips for the next time this happens:
1) Use automatic backup software to backup your most important information to another drive
2) Back up your registry daily - and save multiple days so that you can go back to a previous version if necessary)
3) Use System Restore - there are even ways to edit some files so that more or less can be included in the System Restore folders.
4) Use a disk imaging utility to make a copy of your hard drive - then use it regularly to make a more current copy. That way, with a system crash, you can be back up and running within 20 minutes - using the last copy of the disk image.
