I have a Samsung 32 inch HDTV I like to use as a monitor. When I plug in the hdmi cable directly into the motherboard, I can see the video without a problem. When I try to download the video card's driver however, both with the cd, and trying manual installation, I get the error "The graphics driver could not find compatable graphics hardware." I opened up my pc and realize that the video card is not getting power from the 6-unit pci connection to the power supply. After plugging that into the video card, and making sure the video card is well in place, I try starting up the computer. The computer starts, but I do not get any video when I plug it into the motherboard, or the video card. When I remove the power to the video card via the pci cable, I can see video using the hdmi cable, but only when it is connected to the motherboard. Please help me, why is it that I cannot see anything when the video card is powered by the pci cable?

is it an agp card or pci express?


reseat your card ... and go in bios select GPU at pcie , save , boot and then plug cable to your card
