I just received the updated the service pack 2 yesterday. I'm not sure if that has anything to do with this or not.... Everything was working fine, until this morning. All of a sudden my whole system locked up. I restarted it and it goes to a black screen with an option of hitting F1 to re-boot or F2 to enter setup. F1, does nothing but flash the same message, when struck. F2 goes into the set up screen. I tried to hit F8 while restarting, to get to safe mode, but it wont let me. I also tried to boot up with the WinXp disk and I can't do that either. My whole life is on that computer and I need to be able to at least get on and copy some files to a networked computer. (I am currently on my lap top) Please help if you can.
