I followed your instructions but the problem I am having is that my screen is completely blank, I cannot get to the start menu because it is not there and I cannot press the shortcut keys cause they don't work? I have the mouse pointer and it moves when I move the mouse but again, I have a blank screen. Can you help me?

I could get into the safe mode and command files but even in safe mode it goes blank!

I have the the same problem as one of the anonymous users, I just have a blank screen when I boot up in safe mode. Is there anything I can do from there?

you can get your menu bar back by pressing ctrl+alt+del and then hit file > run and type explorer.exe. This should get your taskbar back if you open to a blank screen.
