Posted December 5, 2019 Hello! Have just built my first PC in absolute years, and it's working - which is a good start - but not with the AMD HD 7700 graphics card that's installed. It will only display anything through the onboard graphics. At first I thought it might be that the card wasn't seated right or is faulty, but after installing Windows, it automatically detected and doesnt lists the AMD HD 7700 in Device Manager. It just won't display anything when I plug in an HDMI lead. I've changed the BIOS to output via PCI-E and nothing happens. I've flashed the motherboard bios to the latest version. Still nothing. To be clear this isn't a driver issue – even the bios won't show up when the monitor is plugged in to the graphics card. The HDMI lead works with a nearby friends's pc on the same monitor so it's not that. I'm totally stumped. It has DVI output as well, but I don't have a lead to test it with. Will try and pick on up today. Here's the full specs, in case it makes any difference: AMD Radeon™ HD 7770 GHz Edition Intel Pentium Dual-Core 2.7 GHZ 8GB (1x8GB) 1333MHz DDR3 400w Plus Power Supply Gigabyte MB ga-g41mt-s2p (rev 1.3) WD 250GB Blue 2.5" Solid State Drive / HDD 1Tb/ HDD 250Gb Only indication that I have that the GPU is in my system is this.

Posted December 6, 2019 Did you check if there is a bios-update available for your motherboard?
