Blank screen - Administrators

Question

I recently had a virus on my computer.  Now I get a blank screen when I try to logon to an Administrators account.  I have 4 user accounts. 2 are standard users and 2 are administrators (1 is the admin that comes with windows). I have no problem with the standard users. If I have to run something as admin while in the standard user accounts, I have no problem entering the password for an admin account and completing what I need to do. The only problem is when I try to logon to an admin account I get a blank screen.  I then hit ctrl - alt - delete and select log-off from menu that appears.  Briefly my admin desktop appears before going to all users login screen.  I have Windows 7 Home Premium.

Answer 1

   It did not work.  Same results. A total blue screen for the newest admin and a total black screen for the other two.  Thanks for your help.

This can mean one of two things:

• Traces of your virus are still present.
• The virus caused some damage in the registry or with some files that have an effect on admin accounts.

To me an infected machine is a compromised machine. I would drop back to the most recent image I have or else perform a destructive Factory Restore.

Answer 2

It did not work.  Same results. A total blue screen for the newest admin and a total black screen for the other two.  Thanks for your help.

Answer 3

Here is what I would do next:

1. Reboot into Safe Mode.
2. Log on under an admin account.
3. Run msconfig.exe.
4. Untick each and every tick mark under the Startup tab.
5. Reboot normally and check if this solves the problem.

Answer 4

Frederik,

     It did not work. I got a totally blue screen when I logged on to the new admin account. I get a totally black screen when logging on to the other 2 admin accounts.  I was able to enter the admin accounts in safe mode. Thanks for any further help.

Answer 5

I would try this:

1. Log on under an ordinary account.
2. Open an elevated Command Prompt.
3. Type this command to create a new admin account:

net  user  admin  123456  /addnet  localgroup administrators  admin  /add 4. Log on as  admin with a password of 123456

Does this solve your problem? If it does not - what happens when you reboot the machine into Safe Mode, then log on under an admin account?
