A few days ago my monitor started having problems when turning the PC on.
Most of the times it would stay black for minutes and then it would show the sign in screen. Now it doesn't even do that, it just stays black.
First I tried the usual stuff (restarting the PC, unplug-plug the monitor, unplug-plug the PC, inverted the display cable, etcetera) but nothing solved the problem. Then I removed the graphics card and booted the PC with the iGPU: no result. I installed the graphics card again: no result. I removed the graphics card and cleared the CMOS: no result either.
I think I should mention that when the screen is black Windows doesn't make any sound, I unplugged and plugged peripherals but it didn't make any sound. That makes me think that it could be something else.
