hey guys. just got a new 6800GT agp to put in my gigabyte 8IG1000 Pro-G mobo and i get a blank screen, wtf. unplug it, put in old 9600XT, blank screen. unplug that use onboard vid, blank screen. funny thing is the comp was working fine 10mins ago with the 9600. no jumpers to disable onboard vid. tried cmos reset. thing is i had a x800 that died in this mobo before the 9600, so mabey teh agp port is wonky or i think this mobo has a problem between a vid card and onboard. i dun know what do you guys think?
