[Stemster]

Computer Type: Desktop

GPU: ASRock Radeon 6800 XT phantom gaming graphics card 16gb
CPU: Intel i9-9900k
Motherboard: Z390-A PRO motherboard
BIOS Version: Latest
RAM: 32 gb ddr4
PSU: GIGABYTE GP-UD750GM 750W 80 Plus Gold Certified
Operating System & Version: WINDOWS 11
CASE: Corsair 4000D

fans spin, lights are on. Monitor not post/detecting it. My 2nd monitor that's plugged into motherboard doesn't turn on either (shows no signal) with the 6800 XT in.

This is my 2nd 6800xt GPU. I RMAd the first one and it still doesn't post. So i dont think its a dead GPU

what I tried:
-tried all ports
-I updated my bios.
-removed cmos battery for 30 minutes
-changed pcie slot from auto to Gen 3 in bios.
-DDU my nvidia driver.
-My 2060 card works fine.

I have no way of testing GPU on another PC atm

How old is the PSU in your build? You might want to see if sourcing(borrow, not buy) a higher wattage unit that has more than 850W of power at your PC's disposal helps alleviate the issue.

BIOS Version: Latest
What BIOS version are you on? We've had multiple people come in and say latest until they realized they weren't on the latest version.

I just bought the PSU from amazon about a month ago, I dont plan on overclocking right now.

bios shows; e7b98ima.1e0, and the date is 2022-11-08
