What you could do is remove his hard-drive from his pc and connect it to yours and copy his files like what ever he cares about like pictures,music ect and then when he gets a new one,copy them over.Also by video card,is it a dedicated video card or on board on the motherboard?If it's dedicated,you could probably still get into by getting the pc to connect through the on board and setting it in the bios to use on board instead and backup his files like that. If it's onboard as in it doesn't have a third party video card and runs off the motherboard alone then do the first option I told you and you could save his files if the hard-drive still works.
