I recently built my first PC, and while it powers on, I'm getting a 'no display found' message when I connect it to my monitor. I've gone through a few troubleshooting steps already:
- Ensured the HDMI cable is plugged into the GPU (I also tried the motherboard).
- Checked that all cables are securely connected (motherboard, GPU, PSU).
- Reseated the RAM.
- Updated the BIOS using flash BIOS.
I'd really appreciate any additional suggestions or help! Thanks in advance for the ideas!

Make sure to check if your motherboard has any warning LEDs lighting up. I faced a similar issue with my new setup, and I resolved it by flashing an older BIOS version and connecting the HDMI to the motherboard, using the integrated graphics from my CPU. After that, I installed the necessary drivers, and everything worked fine! You can find some helpful troubleshooting tips here: [ASUS Support Link](https://www.asus.com/us/support/faq/1042678/). Also, verify the RAM is seated correctly and don’t forget to hit the ‘Del’ key to enter BIOS. Good luck!
Have you tried switching to a DisplayPort cable instead of HDMI? Sometimes, certain monitors work better with that connection type. It’s worth checking out if you have one on hand!
I just tried it and no luck.

I think this may be it. I have a combination of the white and greenish-yellow LEDs on the mobo.
