For the past few days my moniter has been flickering on and off, it happens nonstop and I realise the flickering is matching the power light on my monitor. The flicker on and off is fast with 2 seconds inbetween each flicker. I manage to narrow it down to the cable connecting to my monitor, I have to plug it in and out until it stops flickering. This has not happen before so I am not sure if it is the cable issue or its my monitor issue. But to plug in and out the cable to my monitor each time I turn on my PC is annoying. As I have to do this until the screen stops flickering.
