I'm having trouble with my monitor displaying a 'No signal' message, even though my PC powers on fine. I've plugged the DisplayPort cable into all the different slots on my GPU and also tried an HDMI cable, including plugging the HDMI into the motherboard directly. It worked perfectly back at home, but after moving to my dorm, it's just not displaying anything. When I turn on auto-connect, the monitor cycles through the channels but still says 'No signal.' I set it manually to both DP and HDMI, but nothing works. I also confirmed the monitor works with my Xbox, so I'm guessing it's an issue with my PC. I'm concerned that I might've jostled something while transporting it. Any ideas on how to troubleshoot or fix this?

I’ve run into this issue before. If you have another HDMI cable, it might be worth trying that to rule out the cable itself. Sometimes cables can fail unexpectedly.
Have you tried the shortcut 'Ctrl+P' twice? It can sometimes help to switch between display modes.
If you have an HDMI port built into your motherboard, try connecting the monitor there to see if you get a signal. If that works, you may need to change the display settings to prioritize your GPU.
Just as a heads up, I noticed your PC might be quite dusty inside. That can sometimes cause connection issues. A good cleaning could help, especially around the RAM and GPU.
When you have a display issue like this, it often relates to the RAM. I’ve faced similar problems a few times. You might want to try cleaning your RAM modules with a pencil eraser and then reseating them in their slots. It worked for me once—might do the trick for you too!
Sounds like a classic RAM issue to me. If reseating doesn’t help, you might want to test your RAM sticks one at a time—sometimes one can fail and cause this kind of problem.
OH MY GOD, THANK YOU! THE ERASER THING WORKED! I’m so broke right now and was scared I would need to hire someone to fix it. Thank you so much!
