Three different times I have attempted to repair (install over WinXP). Each time it would go part way and stop, screen goes black, and it reboots. Each time it goes back to the same place, and starts over. It seems to load some things. I think it would go on forever if I did not turn off the power. Going into Safe Mode does not work. I heard from my daughter today, and her computer is doing the same thing. I have my Xp on a separate partition, and can blow it away and, reload it. My daughter does not. Can anyone tell me what she can do to fix this problem.
