ive been havin problems with my pc for a while now...and most recently i can't even get it to load windows...everytime it starts up it says error loading operating system...so i finally got my hands on a windows xp copy and try installing it, formatting and everything and then when it goes to load the setup after i format it still gives me the error loading operating system error, and just doesnt go anywhere from there....ive tried this on 2 different HDD's now so im guessing its not the hdd that's not working and i can't figure out what's wrong. Any help or any other questions would be greatly appreciated.
