I have a 1150 socket Asrock Extreme 3 motherboard. I was using the on board graphics with no issues at all. I bought an AMD video card and had all sorts of problems. The computer would lock up, have no video and other such things. I got another AMD card and had the same results. I decided to switch to an Nvidia 750ti card. I had more issues and decided to do a complete reinstall. I had some issues with the install and had no video. Now the computer will not boot with the video card in it. I have a new Corsair CX600 power supply and 8 gigs of ram. The motherboard, cpu, and ram are about 2 months old. I have the newest bios as well. Any other suggestions? I can get in the bios but not any further. It locks on the boot. When I take the video card out and use the on board graphics all is well. I have built over 150 computers. This is really weird....
