I was talking to a friend of mine and he said if you change any major parts your windows xp won't work there is a thing in there to where it recognizes the hardware like the mobo and cpu and such the main things and when there is new ones it wont work. It was supposibly set up this way to keep large corporation safe from people steeling the hardrives and dumbing the info on there home machine.
As said by Nubius, he is incorrect... to a point. On older systems there was a key lock between the restoration CD and the HDD chipset/BIOS. This was NOT the original XP cd, but a manu CD like Gateway. I don't think they lock it down anymore, but at one time they did. If the hardware ID did not match what the security ID on the drive had, then install was a no go and you would get the error: This is not a Gateway machine.
If you argue with an idiot he will drag you down to his level and beat you with experience.
