upgraded RAM from one 8gb stick to 2 8gb sticks. I have a hp pavilion pc with an upgraded gpu, psu, and hard drive. When originally installing the new RAM the bios could see 16gb, but nothing else could like task manager/dxdiag. A friend suggested updating bios/uefi through drivers, updated that hoping to solve my ram issue, and now I have no output from gpu hdmi port, or the mobo hdmi port. Any ideas???
