Another black screen after logging in thread

[CZucker]

Hi folks,
I'm having some problems with my Windows 7 Ultimate installation.

After applying some Windows updates last night I get a black screen with a pointer when I log on to my main account. CTRL + ALT + DEL do not work. I can't get the task manager up.

Safe Mode and Safe Mode with Networking give me the same black screen. I can log on using the command prompt and then load explorer.exe manually. This gets me a barely usable system. Things happen very, very slowly.

I tried restoring to an older restore point and running the startup repair and neither worked.

Then for the hell of it I tried using my Boot Camp partition as a guest OS in Parallels Desktop. It didn't immediately work, but I was able to use the Parallels menu to send the CTR + ALT + DEL keystrokes and that got me to the regular screen showing me a few options (start task manager, etc). If I hit cancel, it goes to my regular desktop and all seems fine.

However, when I tried to boot from the partition again, I still got the black screen.

I finally tried to log on as a different user and guess what? That worked without a hitch. . . Everything seems fine with any other user.

So in a nutshell:

1. I get a black screen with the cursor whenever I try to log on using my preferred account. The keyboard is not visibly responsive (I think it's doing something when I hit keys, I just can't see it)
2. Parallels can run log on using the user.
3. All other users work just fine.

Does anyone have an ideas?

Thanks,
Chris

I have a similar problem with my machine after updates and then the restart thing. Mine hangs at the revolving graphics and locks up. Nothing works.
I went down the route of restoring to earlier point.
startup repair and etc.
nothing seemed to work.
Sooooooooooo! I finally tried a different approach.
machine still hangs at black screen during restart after updates
so hit hardware reset
boot error message about starting in safe mode or normal
I select normal and it takes off with no problem.
Don't know what is causing this anomaly but "repair" attempts don't seem to work.
Actually just happened last week for windows update. So I knew what to expect!
See my specs for system information
maybe this will help to keep you going at least until someone can come up with a fix. My cure is just a workaround
