The other day my son's computer would not boot properly. He gets the XP logo and it seems to boot fine, but there is NOTHING on the desktop except a black screen and the mouse pointer. ctrl-alt-del does nothing (I think the keyboard is dead too) and right clicking brings up nothing. He tried a repair installation and that didn't do anything. At one point we had gotten a STOP 7B message and re-installed the file that was called for but then reverted to the same problem. I have tried everything except a total re-format and clean install. I'm trying to salvage his files for college, that's why I'm hoping that someone can help me with a solution to this problem. BTW, I had a spare hard drive and we did a clean install on that drive and it works fine, so the hardware aspect of the system is OK. Any help would be GREATLY appreciated.
