WinXP Pro Automatic Login/off

Hey guys, it's been a while since I last posted here, but here it goes:

I recently downloaded a few optimization programs to clean my computer, such as the registry,etc. I think that one of the programs (Reg. Mech) might have deleted a file which is in charge of logging in and out of the computer. Thus, everytime I start up my computer, it automatically logs me off, then auto. logs me on, then off and so on. No keyboard shortcuts such as alt ctrl delete work. Safe Mode also doesn't work. I'm guessing the only way to fix this is to put the right file onto a cd, and boot from the cd..this is just a guess.

Thanks again,

Put your CD into your cd drive and go to Start > Run > and type sfc /scannow.

I cant get to the desktop.

It sounds alot like the Userinit value has been modified.
