Well, maybe it does finish booting, but I get no desktop icons or taskbar.
I have Windows 2000 Professional and it won't boot in normal or any of the safe modes available. It gives me the box that says Windows is starting up, then I get the log on screen, and it gets to the point where it indicates that it is loading my personal settings. After awhile the message goes away and I get a light turquoise screen that never gets populated with any icons or taskbar, or anything.
Most of the safe mode options get me to the desktop with a black background, and 'safe mode' in each corner and... nothing else. No icons or taskbar here either. Even the 'Last known good configeration' fails to work.
In both normal and safe mode I can get to the security screen with CTRL-ALT-DEL to display the options to change a password, start task manager, lock the computer , etc. All of these options work, except for the Task Manager. Hitting that button only makes the security screen disappear.
This PC has no Windows CDs, so I can't access the recovery console. I did use another PC and dowloaded a 4 diskette set of floppies for W2K Pro that I was supposed to be able to boot from, but when I put in floppy one and power up, I get the blue Setup screen, followed by the msg "Ntkrnlmp.exe Could Not Be Loaded. The Error Code Is 7. Press any key to continue".
This was working fine until just a few days ago when my nephews were playing with it.
I did reload all the default settings in the BIOS setup, but got nowhere there either.
