Hey all. My Sapphire r9 Fury X suddenly began acting up. My system will suddenly make a "new hardware connection" sound and all functions will seize up or slow to a crawl and is sometimes accompanied by screen flickers or black screens. When this happens, I found that my system is detecting a phantom non-PIP display that doesn't actually exist. Looking at the advanced display settings during this "phantom" display connection, an unspecified display is reportedly connected to a Display Port (though none are being used). Running a hardware monitor, I also found that the GPU is dropping to 0.900v (down from the normal 1.250v) and the clock speed is dropping to 418hz (down from 1050hz).
-All other system hardware is keeping steady voltage, so I don't *believe* it to be the power supply.
-I have already re-seated the card, reset Windows 10, completely uninstalled the drivers (in safe mode) and reinstalled the newest stable drivers without any of the extra software.
-This problem occurs with either of my 2 monitors connected (each individually, or both simultaneously), and when using different connection cables.
Any idea why this could be happening?
Could be a failing power supply or potentially the video card or motherboard. Run OCCT from OCBASE_com it will run tests and give you a report on those components you can see if they are okay or not.
