System won't post with gpu installed

[Jo31337]

So my system is a evga z490 dark with i9 10900k 16 gb ram thermaltake toughpower gf1 850 watts 80 plus gold gpu is a zotac 2060 super mini. Motherboard cpu and power supply is brand new. System will post and boot to windows if the gpu is disabled. I have tested the gpu on two other boards. Swapped out multiple ram. Uninstaller nvidia drivers to try and fix. Updated bios reset everything multiple times. So I am lost I have no idea what to do talked to evga and they would only tell me they can't help me until I send them a picture of the cpu pins and I didn't twice and havnt heard anything back. Also I forgot to mention when gpu is installed and I click the power button the pc turns on for half a second off than back on all fans and rgb work gpu fans work. Post code is 14 and all pcie leads flash white

Post code 14 can be caused by several things out of your control...and it can be caused by bent pins. That's why they want to see a picture of the pins. Have you tried calling them?

I am sorry i didnt see your reply faster, i ended up RMA the motherboard but everything together on a test bench pc post with GPU but as soon as i restarted my pc samething again. so fresh windows all over again redid all the drivers everything you can think of. Now i can get the GPU to work but i have to reseat the GPU in the PCIe slot if it doesnt work boot the pc with integrated power down install gpu again and sometimes it will work other times it wont. I dont want to have to keep installing and uninstalling the card. It cant be good on the board or the gpu
