Im trying to help my son here , today he got his new board MSI don't really know what board yet . An Intel I5 cpu he's using an AMD 6950 graphics card but the board won't post - no video . I've been searching the internet for answers got one , he put a new cpu heatsink and fan on it . What I read so far is that one of the mounting screws for the hs and fan might be shorting out the board ? my son's very good with computers he's been threw the bios and repeatedly set and reset the bios he can get video threw the onboard video . The card still works he put it in another pc and it posted with no problems . does anyone have any idea's ?
