Your monitor is plugged into the GPU not the motherboard?
If so I suggest trying the card in another PC, if it works there you know it is at least something with your system.
Yeah monitor is plugged into the GPU. My CPU doesn't have integrated graphics, so no other way to acquire signal. And my system works fine with my old GPU installed.
I took it to a PC repair shop and had them test it and they reported the same thing, so it would seem I just have another faulty card, but the odds of that happening twice in a row seem rather slim.
Could it have something to do with the boot settings in MOBO BIOS? I know these cards are UEFI only and I've also read that power save settings can cause them to not boot
Yes it can absolutely be bios. If your board has a newer bios you can try I would. Sometimes setting the board to a combination UEFI and Legacy mode can help.
Sound like a bad AMD &/or Nvidia Driver uninstall to me.
I had exactly the same problem when I removed an RTX2080 OC to replace it with an RX5700XT I was testing.
I ran DDU but forgot to clean out old Nvidia Drivers as well as the AMD ones using DDU.
The RX5700XT powered up in the same way.
No display output, hot GPU. I thought the RX5700XT card was dead. Backplate was roasting.
It wasn't dead..
So just an update, I tried every step in the link you posted and no change at all, card still failing to display and back plate getting really hot. I even did a fresh install of Windows on a new SSD and still no change. I appreciate the link, though.
Did you try different BIOS switch setting on the GPU?
Did you reseat the GPU?
Check the PCIe slot is clean?
What happens if you install it in the second slot on the motherboard?
One other possibility is you might need to reflash the motherboard BIOS in case it is corrupted.
Hope the card is not dead.
Should be still under warrenty if it is though.
So RMA it rather than take the GPU apart.
Have tried both BIOS settings on the GPU and have reseated it more than once. I would assume the PCIe slot is clean since my other GPU works just fine when installed.
I haven't tried the second PCIe slot on the MOBO because the GPU is too big and would block the USB 3.0 port, among other things. Worth a try though.
I updated my MOBO to the most recent BIOS and still no change. At this point, all that makes sense is that it's dead. I guess I'll just RMA it again
