I have been facing this issue for the past 3 days now where the colors on my display would randomly go crazy and start flickering. Here's how it looks like: https://i.imgur.com/Ti23FYE.jpg When this happens, even the in-built display menu colors messed up. This is how it looks normally: https://i.imgur.com/QMvHcqO.jpg but the colors become messed up even for this menu. If I detach the HDMI cable during this, the display keeps flickering for a few seconds before going back to normal. Things I've tried: - Switching HDMI cable - Connecting to a different HDMI port on the display - Detaching GPU and connecting HDMI cable directly to motherboard - Connecting laptop and DTH to display. Worked fine for over an hour - Connecting PC to living room TV. Worked fine for 7-8 hours of gaming This does not happen frequently so I can't nail down what the issue is. It could very well be that the display decided to work fine when I connected the laptop/DTH and same for the PC when I connected it to the living room TV. Another issue I have been facing since this happened is sometimes when I'm playing a game (happened only in Rainbow 6 Siege so far), the PC would lock up for a minute or so and then would go back to normal. It felt as though the PC was severely struggling for a minute (I'd get 1 frame every 5-10s) and my audio/mouse would freeze as well. What could be the issue here? What are some of the steps I could take to troubleshoot this? Please help me, thanks!
