It was working fine before I packed it and mailed it to myself across country. After I opened it up and hooked it into my new Monitor (Acer HR274H) via HDMI and I was getting no input to my monitor but the fan on my GTX 560 Ti was still running. I switched the cable for a VGA (with -> DVI adapter) and I could see the BIOS screen and the Windows logo but then after that my monitor would stop receiving input. I tried hooking it up to my TV via HDMI but got no input at all.
I assumed that it was my graphics card so I pulled it out and reseated it, that didn't work.
I then started in safe mode and checked my GPU in Device Manager, and it was fine and Windows couldn't find updated drivers. I updated my graphics driver to the latest WQHL release from the NVidia website amd that started my Code 43s.
Instead of a blank screen, after the Windows logo I'm getting a 600x480 resolution screen with really messed up color. When I check in Device Manager, my GPU has the Code 43 error.
Did I bust my card? Or anyone have any other advice?
I was getting a code 43 error after installing Catalyst drivers but I'm quite sure the issue you have with the code 43 is the same as what I had. Multiple video cards in your registry. Follow the instructions on the link should solve your code 43 error and possibly your no video issue as well.
