I have encountered a major problem with my computer setup from around 20th May this year (or just before.) Basically, the displays goes black all of a sudden. The displays show a "No Signal Detected" warning then go into standby. The computer fans speed up momentarily, then slow down to "normal" speed. The computer remains running with no display showing. Nothing brings the displays back into connecting with the graphics card, until I reboot the computer.
On reboot, the main monitor (not the secondary monitor) starts working with the generic Microsoft drivers. The Radeon display adaptor driver has been disabled by Windows with code 22 device status. If I uninstall that driver and reinstall via scan for hardware changes , then the Radeon display driver takes back control, and both monitors then display properly. ... But same issue reoccurs again, and again, and again, every day and usually several times a day as well.
Dxdiag reports "No problems found."
Switching to single monitor only does not resolve the issue. I haven't touched any cables. The configuration was working, now it isn't.
The problem originally occurred when launching a game. Then several days later, the problem "spread" and affected all games and the windows desktop and Internet use. I can no longer launch any of my games as the problem kicks in upon game launch/game start menu sequence. Tried clearing out the Steam Cache and Verifying game file integrity. Tried running a long Full Scan (Microsoft Defender). Scan reports "No current threats."
What is causing this to happen all of a sudden? How to fix?
