I’ve been trying to solve this by myself for the past day and I have no other options left.
I recently upgraded my CPU, MB, and RAM. Everything was successful but after I logged in I noticed micro stutter. I installed chipset drivers and the last thing I thought about was updating the Adrenaline drivers. I had 24.3.1. And I updated to 24.4.1. During the screen flickering, my monitor went black. I waited about 5 minutes since it says install was had 1minute left. I did a hard turn off on my front panel and power back on My GPU now has no display output whatsoever. MB VGA red light comes on every time I power on with the 6900. I switched to my older rx 5700 and it works fine. I reverted back to the old drivers and still no imput from 6900.
