Hello,, I have a Toshiba Qosmio G35-av600,, I think my Video or graphic card is out,, I get a blue screen. and it says something about the bios,, I was wondering if the video or graphic card is out,, and is it a card or is it integrated on the motherboard.?? or is there a video card or something a person can remove and replace it, and with it work if I try a external montor to it..? thanks
