For a while my GPU worked perfectly fine but recently my display randomly started flickering.
To elaborate: the screen suddenly turned black for a split second, then returned back to normal. The first time it happened, this repeated about 3~4 times roughly once per minute. After that the display just cut off completely (displays "Entering sleep mode" alert) and hasn't returned back to normal. The fans were still running and audio from my running apps still played, just the screen turned black.
When rebooting the PC, only the initial OS logo appears as it should and once the loading completes, the screen just goes black and enters sleep mode again.
I can't find anything unusual when checking Event Logs around the time the display completely cut off.
What I have tried so far:
I could really appreciate any kind of advice that could help me resolve this issue.

What I have tried so far:
■ Unsocketed the GPU from the motherboard, blew the dust particles out and cleaned it, after socketing it back on the motherboard it seemed to work for a short time before stopping again.
■ Used a different monitor, DVI-D cable and tried both the DVI-D and DVI-I ports on my GPU. I now have a second monitor (let's call it Monitor B) connected to my integrated GPU so I can work on fixing the problem while the Monitor A connected to the AMD GPU doesn't function.
While my AMD drivers are enabled, Monitor A shows a black screen and Monitor B works fine. Moving the mouse cursor or any application window from one screen to another isn't possible. Both Windows and AMD software don't detect Monitor A.
If I disable the AMD display adapter through Device Manager, Monitor A starts working on the integrated GPU. Windows detects the monitor now while AMD software doesn't (since the GPU driver is disabled).
■ Ran the OS in safe boot mode (surprisingly enough, the display worked perfectly fine in safe boot) where I completely uninstalled AMD drivers using AMD Clean Uninstall Utility. After rebooting normally, the Monitor A display was still blank even without any drivers while Monitor B worked as expected with the integrated GPU. Even after completely reinstalling all the latest AMD drivers and restarting the PC, there was no change.
