Im sure there are alot of things that can cause this but ive looked and really havent seen anything that could narrow it down thought somebody could help me

First off I'd suggest a system restore to a point prior to your problem:

start > All Programs > Accessories > System Tools > System Restore

If you cannot boot into XP in order to do this try Safe Mode then take the system restore option presented to you there:

Safe Mode

Can you get into Safe Mode?
