i have the sapphire radeon 7790 oc 1gb card, i got a new psu and put it in my case and hooked everything up, when i fired up my pc the monitor couldn't find the display, i switch the dvi cable to the motherboard dvi connection and it turned on, the video card is powering up though, i get into my account and a message saying it couldn't find the video card driver popped up, i went to install the driver but every time i install it, it goes through its thing then a message comes up "some warnings came up" or something like that, if anyone could help that would be great
oh i have windows 7 64bit if that helps.
