This is so frustrating. I have been running windows XP and all of a sudden sometimes it wont boot even after 10 minutes, other times it takes more than 15 minutes too boot up. I got in safe mode and ran the defrag and there were no problems there. Finally when it booted up I ran a virus scanner just to be sure, no viruses found. Then it happend again, so I went back to a restore point... still it does not boot and if I am lucky enough to find it boot it takes 10-15 minutes. Can anyone please enlighten me and tell me how to fix this ???
