Hi! I am such a serious rookie with this stuff that I literally fried my motherboard because I put my RAM in backwards. In my defense, it clicked in like it fit. Really all I need to do now is get my harddrive into a new place so I can keep using it. It's got win xp and all my data. I have another computer I don't use that runs fine, tho it's old...it's only running win 2000. Can I just switch out the harddrives? OR, can I transfer my xp info onto the harddrive that's already in the other computer? How do I wipe the win2000? The worst part...I don't have a product key for win xp. Sorry for the convoluted questions. Any suggestions would be appreciated.
