I would do extensive testing with the other card before sending your old card in to rma as the problem might show up again at a random time. Last thing you want to do is rma your card and get back a card that may have more issues than your current one.
Yes, sure, the cards from RMA are "reconditioned", right ?
I'm having the identical issue with an Asus Crosshair VIII Hero (WiFi) and EVGA 1080Ti ftw3.
After weeks of fiddling with it I found that it is temperature related.
Once my VRMs hit ~80c the system will NOT restart.
My monitor gives a orange light and the VGA light stays on on the motherboard. I can however login to Windows with the screen off via muscle memory and it will boot right in.
I can restart the system and it'll either boot right up (once the card cools down), or I'll get the 'vga card not supported by UEFI driver' error (if it's still too hot). Everytime I get the UEFI driver error, CSM is enabled automatically.
What I've noticed also is that when the screen doesn't come on at ALL, the BIOS still enables CSM, but the error doesn't pop up, nor does anything else.
In my case enabling CSM doesn't resolve the issue, but it will restart at higher temps with it enabled than it will with it disabled.
What's crazy about all of this is that the card works perfectly once I'm in Windows. Hell, it even holds a 2ghz OC and stays under 72c at all times.
This is officially the strangest troubleshooting issue I've ever seen in 20+ years of PC building.
Stranger still, I put a multimeter on the card and everything checks out. I can't find anyone locally who can fix the card either, and trying to score a 3080 right now is IMPOSSIBLE.
I haven't been gaming on it because I don't know if it's safe. I'm assuming it isn't because something is clearly not getting adequate voltage.
The last thing I want to do is fry 1000$ worth of other components.
TL;DR The UEFI bios of my GPU isn't being read properly when my GPU VRM hit's ~80c or higher.
