Sapphire Vega 56 won't install after a successful installation 2mo ago.

Question asked by fubar1764 on May 25, 2020

Trying to install Sapphire Pulse Vega 56 onto ACER ATC-780-AMZi5. PSU upgraded to Corsair CX750 (750w) so power isn't the issue. After several frustrating unsuccessful attempts, I got the GPU working (not sure what happened. . .suspect luck), then turned off the HDCP to get rid of the flickering. Every so often, the bluetooth audio would mess up, but it would troubleshoot itself. This last time, it didn't troubleshoot itself. So, I figured I'd reinstall the driver. There was a bunch of other junk I wanted to clean up so I wiped the windows install back to a fresh one. I installed the video driver. Now I can't even get signal. I've installed successfully (moved things and remembered keystrokes) so I can install while not looking at an image on the screen. Nothing. Suggestions, please!

Note: only monitor is a 55" tv, so only using HDMI.

Driver is Adrenalin 19.12.2
