So I bought Sapphire R9 280x Tri-x.
So when I tried switching first time the GPU didn't post. I had Windows 10 installed with MBR and I read that it can cause problems when switching GPUs. So I reinstalled Win 10 to GPT. Right after reinstall I switched the GPUs and the R9 280x posted and I log in to Windows. Then I installed drivers and the installation restarted PC. And the GPU wouldn't post again. What should I do? I don't think that the GPU or the port is broken since it posted once and it worked normally.
The photo shows the diodes that the GPU shows right now, if that helps. Also I'm switching from RTX 2070. Tomorrow I'll get a mini display port to display port and see if that solves it...
