My father has been trying to fix a friends pc. He had a problem when formatting with the win xp disc (it would hang just before it got to the formating options). He was trying to sort it for weeks to no avail when for some reason he swapped graphics cards. It worked after that. When he put the other one (radeon 9600) back in it would'nt work again. My best guess is that the graphics card is incompatible with the motherboard and he needs to get a newer bios for it. What does every one think?
