I do play games I built the pc for gaming.

I will start from the beginning because it is confusing.
Build that I have the problem with was..
R5 5600g…
MSI RX6750XT..
MSI B550A PRO.. inthen had the error 45 gpu not detected issue, thought it was the gpu so I got another rx6750xt and, that did not recognise ?
Then bought new motherboard with latest bios for 5600g cpu gigabyte b550m ds3h v1.4
Still not recognised ?
Whiped the pc & m.2/installed windows again/installed drivers again. Used DDU to uninstall drivers then I manually installed chipset driver from gigabyte website/installed drivers for gpu from amd official site to no avail ?

Summing up…
2 gpu both work but not on my system ?
2 motherboards with the exact same issue with detecting gpu in pcie slot in bios ?
2 new psu both work fine.

I’m going insane Lol my mental Health is suffering

I think it’s the pc case lol I have the card showing up now but only in the bottom slot ???
Progress all the same .
I’m going to strip it all down and go again outside of the case

Make sure all of your headers are plugged in correctly.

Reference your motherboard manual and make sure they are fully seated. Especially the power connectors (on the PSU side as well if it’s modular).

Make sure when you strip down to inspect the components. Look for bent CPU/socket pins, any damage to the RAM/slot or GPU/slot. A can of compressed air to dislodge any dust in the slots wouldn’t be a bad idea either.
