XP reboot loop / Admin password not recognizd

 beren1155 -

This morning when I rebooted my computer, Windows installed an update.

When I rebooted, my PC went into a reboot loop.

During one of the reboots, I pressed F8 to go into Safe mode, but the computer would reboot at the file


I went to the AVG forums and found that AVG has been causing people problems. I followed the AVG instructions to disable all of the AVG-related files via repair mode. My PC still would not open Windows. Rather, it now got stuck at mup.sys

I then followed the instructions here:


Doing step #11, I used the highest number (24 in my case) then followed the rest of the steps. I think I should have used restore point 23.

When I rebooted, it went back into a loop. When I tried to go to Safe Mode, it would stop at AVGIDSxx.sys again...

I rebooted with the XP cd in again and went into repair mode... but this time, it won't recognize my administrator password.

I am posting from my laptop.

I am stumped.

Does any of this sound familiar? Did I somehow change my password?

The very same problem occurred to me. It looks like the event began with an automatic OS update. Now, I'm also stuck in the reboot loop.

Normally, I have a recovery disk and image to recovery from along with a current backup. In this situation I don't. So, it looks like the best option will be to install an addition edition of Win XP on the box.

It will then be a dual book box (one OS inoperative) and the other workable. The later will be used to repair what appears to be a defective deriver.

Best regards to all,

Thank you
