(especially if an update is indeed the cause) is an "in-place upgrade" (also called a "repair installation"). Read ALL of the following link carefully:
You should also make use of the Recovery console to run CHKDSK /r before doing the in-place update as this might also solve the problem.
I am running Windows XP on my system.
Everything worked find until last night.
Last night I downloaded the following updates:
I ran my updated anti-virus program (PC-Cillin) after installing the updates and before shutting down my computer.
The next morning I turned on my computer and it went to a logon screen. I clicked on the one profile assigned to my computer and it logged on for maybe 3 seconds then went to the screen and would say "loggin off" under the profile. Then I would have to choose a profile again. It is the ONLY profile on my system. The profile does not have any passwords or anything set to it. I can't figure out a way to bypass the logon screen.
In fact safe mode just shows a bunch of command prompts in the dos-type screen. It stops loading after that and all you see is the screen with all the command prompts on it. So I can't access safe mode at all.
I'm not sure if the updates screwed up my system or what. I can't even get into my computer to uninstall the updates. The only thing I can do is load my harddrive as a slave drive on one of the other computers I have and I can access files. I don't know if I can do anything from that screen?
Any pointers or ideas? Like I said, I can access the files on my drive when I move my harddrive to another computer, but otherwise my computer is unaccessible when booted from this drive.
Thanks for any advice you may have. I need access to my computer desperately and don't really want to deal with the headache of formatting the drive and re-installing everything (which is my last move).
