My compaq 2000M laptop is runing very very slow. It ran so slow it went to blue screen I had to go to F8 bios startup to get it to boot to windows XP and it will run for almost 30 minutes before I get to the windows log in page. What am I looking for. Do I need a new CPU, is there something fried on my motherboard? I defraqed, ran clean boot, deleted every file I don't need.
