I recently relocated my entire PC setup outside my room for a thorough cleaning and then brought it back in. Now, my HDMI ports aren't outputting any signal. My monitors are functioning properly, and I've confirmed they're on the correct input. When I connect the HDMI cable from one monitor to my PC, the monitor lights up briefly, but then says there's no output.
The PC powers on just fine and works as usual. My keyboard, mouse, and microphone all function properly via USB, and my monitor even detected a DisplayPort connection. The only issue is no signal from the HDMI ports. I didn't drop or damage anything; it was just a simple relocation. Any tips to troubleshoot this without needing to take apart my whole setup?

Just to clarify, when you say you cleaned the setup, did you actually clean the PC itself? Because it sounds like you moved things around a lot. You might want to verify that your GPU is still seated properly. If it’s come loose while you were moving things, it could cause the HDMI issue.
Check if the GPU is still connected securely; that might just be the issue!
Make sure you’re actually plugging the HDMI cable into the graphics card instead of the motherboard. Sometimes, it can be a simple mistake and you might not even realize it until you check!
Omg I am so freaking dumb lmao. Thank you so much!
Have you considered moving the setup out and back in again? Sometimes simply resetting everything can help.
