Hey folks, I'm working on my second PC build and I've managed to boot it up successfully, but my monitor isn't showing anything. The fans are running, the RAM is lit up, and the GPU fans are spinning too. I have a QLED monitor that indicates whether the PCIe cables are properly connected, and I can confirm it's seated correctly in the slot on the motherboard. I've already tried a bunch of troubleshooting steps:
- Resetting the CMOS
- Using a different HDMI cable
- Testing a different PCIe slot on the motherboard
- Trying with just one stick of RAM
- Ensuring the HDMI is connected to the GPU, not the motherboard
- Updating the BIOS
I feel like I've been at this for hours and I might be missing something. Any assistance would be super appreciated!

Have you tried connecting the HDMI to the motherboard instead? It might help to see if that could be causing the issue. Also, if you have another monitor handy, give that a shot to rule out any monitor problems.
What parts are you using for your build? Sharing your components can help others troubleshoot better.
