Hello guys. My AOC monitor suddenly stopped working today, when last night, everything worked fine. The light on the monitor remains yellow each time I restart or turn on my tower. I tried switching from DP to HDMI cable - nothing. I tried connecting a TV via HDMI slot, and still said no signal. I cleaned the RAM sticks - nothing. I changed slots to my GPU (Sapphire Radeon RX 590 8GB) and still - nothing!! I bought my graphics card almost a year back, so it's not old enough to have issues. It happened to me before, but when I restarted my PC it worked just fine! What can the issue be? Is there anything else I can do? Thank you, in advance.
