Black screen when entering Windows XP logon-screen

  1. My compuper starts up as normal. It boots and shows the Windows XP-logo when loading. The problem occurs when I get to the screen where I can (or in my case could) log on with different users.

    The screen gets black instead of giving me the logon-screen. But I can move the white mouse pointer around the black screen. If I leave the computer for a while (about 3-5 minutes) it shows a error message which is something like this: "winlogon.exe - application error" and it mentions something about "referenced memory" "Press OK to terminate or cancel to debug".
    I can press OK or cancel, but neither helps me.

    I installed Windows XP SP2 a week ago. Could that be the reason leading to my problems?

    Yesterday I tried to upgrade my Windows-installation with a XP SP 2 installation CD. This helped me as i then could enter Windows as normal. Everything appeared as before. But when I started my computer today the same black screen appeared.

    Anyone got some tricks or solutions to this problem?

    The same problem occurs in safe mode. I can only access my machine via the "safe-mode with command prompt". It was from here I repaired/upgraded my Windows-installation

    why dont you run a repair / upgrade AGAIN... this time -- when you boot into Windows OK - scan your machine for viruses / spyware etc

    as per here:

    if all else fails - then you will have to bite the bullet and reinstall Windows in it's entirety!
