I'm trying to fix my sister's computer, as it has a lot of problems, the main one being it won't boot in any other mode than safe mode, in normal it boots normally until it reaches the windows xp logo with the loading bar, then it just shows me the curser in the middle of a black screen and it just stays like that, so I can't actually see what viruses it has and what else is wrong with it.
If you could help me out it would be much appreciated.
