Hey everyone, I'm having a frustrating issue with my PC. It powers on just fine—fans are running, and the keyboard and mouse light up—but my monitors aren't connecting at all. They just display a 'no signal' message. The problem started after I accidentally unplugged something in my wall outlet yesterday and plugged it back in. I'm looking for any help or tips to get my monitors working again. Thanks!

It could be as simple as a loose cable. I've had trouble with HDMI connections before; they can wiggle out. Make sure the HDMI or DisplayPort cable is secured into both the monitor and graphics card.
Also, check if your monitor's input is set to the correct source—switching to HDMI can sometimes do the trick if it's set to another input.
I think I saw you mentioned trying to connect the monitors. Did that not work? Sometimes just replugging everything in or switching cables can help. Maybe give that a shot.
You might just need to get a new PC. 😅 If all else fails, maybe it's time for an upgrade!
Here are a few things you could try:
1. Restart your PC again; sometimes a simple reboot helps.
2. Make sure your monitors are plugged into the correct GPU ports—try different slots if needed.
3. Test using a different electrical outlet.
4. If you have multiple PCIe slots, try switching to another one. That helped me once when I had a similar issue!
Also, don't forget to check if the CPU power cable is properly connected. I overlooked that once and my setup powered up but wouldn't show anything on the display.

I totally agree with trying a different PCIe slot! I had that same issue and didn't even realize my motherboard had two slots. It was a third party who figured it out for me!
