Windows 7: BSOD when switching user

Microsoft Windows 7 Professional x64 Version 6.1.7601 Service Pack 1 Build 7601
 
 

and one thing I want to add is that even when performing a clean startup ,boot time takes 95409ms = 95 seconds. I don't know if this is relevant, but from event log:

Code:

I noticed that the version number of these files are all 6.1.7600.16385, should they necessarily be 6.1.7601.XXXXX? cause I have SP1 is installed.

I don't know your reasons for not being able to reinstall, so excuse me if this is not an option: Repair Install

Basically an upgrade installation right over your current one.

Try Safe Mode, see if you can log off successfully from there. Keep in mind the Switch User option is not available in Safe Mode.

I only have the ISO image of the retail version of W7, so I guess I couldn't do a repair install?? (everything is set up by another Administrator of the computer, who is a programmer and would be overseas until fall) I'll try doing it in safe mode.

I CAN log-off in SAFE mode, and I tried for about 5-6 times, no problem apparently...

an update: I cannot log in to a non-Admin account, when I log in, it immediately log off, with no error message.
I can log in to an Admin account and switching user/logging off still causes BSOD.

It seems a user profile is corrupted, but let's do a repair install. If you have the ISO, mount it to a virtual drive such as Virtual CloneDrive. Copy all the files to a folder on the desktop, and then launch the setup.exe file. That should get you your repair install.

I will try repair install later because I am seating in a very important public examination. But I wonder if I could save my activation status just in case.

Doing a repair install won't cause activation problems if you have a legitimate Windows key; if you're concerned, though, you could create a backup first. The best way to do that would be to create a full system image on a different drive.

I don't know what happened, I didn't do a repair install yet, for no reason I wanted to re-install the display drivers first and I saw something called "Windows Live Display Driver" under the display adapters directory of the Device manager, and I just want to see what happen if I re-install the Driver of it, so I uninstall it and reboot.
After that I can't find it in Device manager, no unknown device or something like that.
And to my surprise, I didn't get any BSOD when switching users for like 10 times, I even hibernate my PC and try the "switch user" option(it was always causing BSOD), no BSOD now, YIPEE!!! I really hope it will never come again. But I don't know if what I did would lead to any other problem, apparently not. And it's interesting that I can't find any information regarding "Windows Live Display Driver" in Google, I wonder what exactly it is and why is it on my PC.
Thank you Jonathan and DeanP for following up my case!!

Despite no more BSOD, I still cannot log into a Standard account. (a new account did not work too) Please help~
Is it because of me trying to log into a standard account in Safe mode the other day???

Is the "Windows Live Display Adapter" related to a webcam at all?

What happens when you try to log into a standard account?
