I had the same problem a few days ago. I installed Xp Pro and As it I saw the Windows start and the Screen goes black and Nothing. I played around with an rebooted and Press F8 before windows logged on. I first tried safe mode and the desktop load and task bar. But that still did not solve my problem. Rebooted, and hope for the best. I still got the black screen. This time after I rebooted I press F8 again this time instead of choosing safe mode; I chose enable vga mode, and windows loaded normal except at a 8bit resolution when I tried changing resolution the computer froze.
How I fixed was I went to control Panel/system/hardware and when to display, there I found my video card and another vga driver when I disabled the generic vga driver. I rebooted my video Card took over and Black Screen Went away. I hope this help.
