I've been having an issue for quite sometime now, I've managed to find some slight workarounds for minimizing the issue temporarily, but it always comes back. I have a dual monitor setup and occasionally I will have one of them flickering randomly. The one that messes up has mainly used a display port connector while the other one uses an HDMI port, I only have one HDMI port on my motherboard so I have also tried using a display port to HDMI cable and the issue still persists. I tried switching the cables and using a different monitor with the same setup and the issue transferred to the monitor using the display port as well as the other display ports on my pc, so I don't believe the monitor is the issue. I use to have a monitor that used a DVI cable and there wasn't any monitor issues, but I had issues instead with my other peripherals. Outside of the monitor, I also have issues occurring with my webcam and keyboard and mouse, sometimes they will freeze or wont turn on until I unplug them and put them back in. I have also upgraded my motherboard, processor, graphics card, power supply, and storage and the issue persists. I tried using a different cable to the power supply and a different outlet to no avail. I think the issue may have started after a power surge, but I'm not 100% sure. Any help would be appreciated.
