Device fails to connect or display output on all screens.
Hey there, I see you're having some tough issues with your PC. Let's go through what you've done so far and see what might help. You mentioned the power cable was knocked out, but it still boots black—no error messages, just a blank screen. The monitor works, so the hardware is likely fine. You've already tried resetting the system, cleaning components, swapping RAM and GPU, even using different cables and power sources.
Since you're still stuck, I'd like to know more details: Have you checked for any signs of overheating or loose connections in other areas? Also, is your monitor showing any error codes or beeps? Sometimes hidden codes can give clues. Let me know what you find, and we'll figure this out together.
Remove the graphics card and connect the display cable to the back of the motherboard. Check for a display connection.
Install a single stick in DIMM_A2 only. Disconnect all other peripherals except keyboard and monitor. Verify that the 8-pin and 24-pin power cables are securely seated on both motherboard and PSU. Restart the device by either turning off the PSU switch or unplugging it, then pressing the power button for 30 seconds. After that, either reset the switch on the back of the PSU or reconnect the power cable to attempt startup.
