Hi gang,

My computer and two monitors have sat unchanged for a year now. However. starting yesterday my first monitor fails to turn on properly, but also perpetually attempts to do so. My PC goes to dual monitor layout for a few seconds (but the first monitor is still black and not really on), gives the annoying 'beep boop' noise of new hardware connecting/disconnecting to the computer, and then reverts back to single monitor layout with my working monitor. This occurs every two seconds, rendering my monitor currently worthless.

It started yesterday, but unplugging and replugging the monitor solved the issue. This is no longer the case today. I cannot try to use any settings options to attempt to analyse the problem while the monitor's plugged in because the dying one is my 'main' monitor and Windows 10 thinks it's hilarious to shift all windows to the main monitor when it turns on.

Please help! Is it the monitor? The cable? Something to do with my GPU? I'm very lost.

Thanks!
