New Vega56 Issue - Windows loads with Green Screen (Driver issue?)

[EdButler]

Hi All,

I recently took delivery of OCUK's fantastic Sapphire Vega 56 offer. I removed my old GTX1060 to install this new card.

The computer booted and displayed the BIOS/loading screen just fine. After a long black screen (presumably installing drivers) the display finally showed at ~700x500 resolution.

I rebooted the PC and it switched to 4K native resolution and within about 10 seconds crashed with display corruption. Subsequent reboots into Windows just show a plain dark green screen, sometimes flickering. (note: this isnt like a green version of a BSOD that i've seen online!)

I've tried booting into safe mode and running Display Driver Uninstaller (hello old friend!), and it temporarily fixes the problem. The moment i install new drivers again however i get the green screen back.

I've seen various similar issues online but cannot see any solutions. Does anyone have any idea what maybe the problem? Many thanks for reading

What monitor are you using, HDMI or DisplayPort? Could you take a screenshot of the issue and see whether it shows up in the screenshot?

Which model is your Corsair PSU and how old is it?

As the 1060 is a low end GPU where a Vega56 is high end and needs a good PSU to run properly.
