i was at a friends house and we wanted to use his brothers computer, we turned it on and got no picture on the monitor. so we looked inside the case and saw the video card wasnt in the socket so we plugged it in, turned the computer on and we got a picture, but it said "please insert system disk". we restarted it and got the samething. my friends brother thinks the motherboard was scratched and that he needs to get a new one now. do you guys think that's the problem or do you think its something else. cause if its something else i wanna tell him so he doesnt have to get a new mobo.
