Reboot loop

I was trying to get my sister's computer running. It is the worst case I have ever seen. It was giving me pop-ups trying to open control panel. It will not let me run Spybot, Malwarbytes anti malware. Folder options are gone from control panel, among other things. I tried a to run these programs. Went into safe mode.....would not let me run them there. I downloaded CCleaner in safe mode and ran the cleaner.(not registry cleaner) Now it's stuck in a reboot loop. What can I do to get it back to at least booting? Any help would be great. Never seen this before.

This is XP media center edition

When I first got there it was popping up "my documents" from a user who didn't even use the computer about every 5 minutes.

That sound pretty bad. I don't know exactly what you have but I often use HiJackthis to solve odd virus/security breaches on pcs.

And if your not able to boot at LEAST into safe mode:

1-looks like you'll have to scan it with another computer.

or

2-backup the important information and re-install

I finally booted into safe mode and changed the name of the SpyBot exe. That allowed me to run it and clear out a lot of the crap.

"My Documents" still comes up on it's own. The computer can just sit there and it comes up again and again. Strange virus. I will use Hijack This and post the results on a forum that allows the logs. Thanks.
