hi scoliosis,
hmm....as for the windows xp bootup problem, try fixing the master boot record and see if that works out for fine for you. what you need to do is to bootup with the windows xp cd. dont forget to change the first boot device in the bios to "cdrom" so the comp can boot to the windows xp cd.
when the comp boot so the cd, in the main console of the windows xp cd, choose repair. then the computer will ask for you an admin pass and if you dont have one, just simply hit enter to skip it. then on C: type in "fixboot" or "fixmbr" either one is fine since they both yield the same result. it should only take a second for this process and afterwards, restart your computer and bootup normally into windows. see if this fixes your problem.
also do you got a spare power supply you can test on your computer?
