Windows xp won't start. The screen where you have safe mode, last known configuration, and stuff comes up. If I try to go to safe mode a lot of text comes up then it gets stuck with the text on it forever. If I go to last known good configuration, the screen turns black. If I go to start windows normally, the screen gets stuck right where it is. I thought that maybe something was strong with the computer so I thought restoring the computer would help but it didn't. I have a compaq laptop. Please help me.
