Hello, I'm new to all this. I have a 7-year P3 computer which was having all sorts of problems & slowed down to a snail's pace so I decided to re-format it. I inserted the Windows XP Pro & it prompted me with diffrerent options so I chose Install Windows XP. It was going smoothly until it was in the process of installing Windows when the screen suddenly turned blue & just froze there. After waiting a while, I re-booted & it went through the same process each time. I couldn't turn it of because each time I would hard boot, it would just start up again. What can I do?
