I have a 3 year old HP Compaq and the onboard video card started burning and now i get no picture. I want to copy some files off the computer before the burning destoys the rest of the motherboard (i can hear start up sounds when i turn the pc on). How can i do this? Best Buy said they can turn off the onboard video card so i can put in a new one, but will charge $50 to do it. And of course even if that works i've got the problem of the motherboard burn spot slowly enlarging when the power is on. I know, i know, i should've back up the system more often
