Hi all, 


First of all, my build:

    • Desktop

Last night, both of my 2 screens started flickering with this snowy, static-like pattern, colours would stretch, artifacts were appearing. You can see in the attached screenshot, although in real time the pattern appeared more chequered.  


I've found through trial and error that uninstalling the Radeon RX 480 drivers & software resolves this issue on my main screen, but my secondary screen turns black. 


Reinstalling the driver restores the secondary screen, but also causes the flickering snow to resume too. 


I've tried reinstalling a few older versions, changed the refresh rate through the Windows display adaptor, cleaned old installs with DDU, and I've tried physically reinstalling the card itself after a good clean, but none have fixed the issue.


At this stage, I'm wondering if the graphics card itself has just burned out? I've seen some other threads online suggesting overheating can cause this, but I wasn't playing any games when the issue first started. Could it be a software issue instead?


Any insights/suggestions are much appreciated.
