I am working on an HP laptop running XP pro that is driving me crazy.  It boots up normally to the Login screen where it is asking you to use Crtl+Alt+del to log in.  If you log in at that time then the computer continues to boot correctly.  But, if you step away for a few minutes and leave the computer without logging in, the screen goes to black (but with backlight on) and no cursor and frozen. can not do anything.  I tried system restore back before the problem started without any luck.  it seems fine in safe mode.  I scanned it for viruses. I changed power and screen saver settings to never.  Please help before I through this out the window.

try to remove some start up programs and services by typing msconfig and then startup and services the two tabs remove the unwanted programs and then try to see if the problem persists.

Disable APM - Advanced Power management in the system BIOS, and see if it makes any difference.

You can also try to download and install the latest motherboard drivers for it. That should update the APM drivers too.

Could be a service issue, stop all non microsoft services up and try again, if it's ok, add them in again 1 by 1 until you find the culprit ;

At the Windows Run type msconfig.exe to open up System Configuration tool.
Then, click on the Services tab and tick the check-box of “Hide All Microsoft Services” to easily locate all non-Microsoft Windows services.
Uncheck all of the non microsoft services

restart

I already tried removing all startup items and no change.
I did not try disabling all non-microsoft services.  I will try that now.

Ok, sorry about the delay but it takes about 15 minutes.  I unchecked all startup items and Non-Microsoft services and rebooted.  It booted up to "Press CTRL+ALT+DEL to log in", I left it there and did not log in and after about 15 minutes the screen went to a black but bright backlit screen, no cursor and no reaction to any keys, mouse or Crt+alt+del. NO Change

you mentioned that if you start the computer in safe mode this behavior doesn't occur, this mean that if you run the computer in safe mode not all the services are running which means that it might be one of the services that push this behavior.  you can try this to make sure that one of the services is causing the problem by running the msconfig and choosing the diagnostic startup then restart your pc and check if the problem persists, if no then start adding the services one by one and restart your pc until you experience the problem again then you can clearly identify the cause of the problem.

Thanks groznywonzy.  That was right on.  I have to admit that I did not realize that there was a different Screen Saver for the Login Screen.  I disabled it and problem solved. Must be a damaged screen saver.  Thanks So Much.  I was ready to backup, reformat and reinstall Windows.
