I just built a new PC, and while everything powers on, I'm not getting any video output to the screen. I noticed that the RAM doesn't light up because I need iCUE for that. I've tried various configurations: using one RAM stick in the A2 slot, testing the system both with and without the GPU, and even flashing the BIOS multiple times. Initially, I used the latest stable BIOS (version 3827), but it seemed to fail since the LED remained solid green. I later switched to the latest beta BIOS (version 3841), which seemed to work since the LED turned off. I also toggled between the HDMI ports on the motherboard and GPU and cleared the CMOS. The motherboard doesn't have any troubleshooting LEDs to help diagnose further. The PC stays powered on, with the fans running, so I'm doubtful the CPU is at fault. However, when I used an older stable BIOS file (version 3602), I noticed the LED blinked a bit faster, which led me to believe the CPU might not be detected. I reseated it, but that didn't resolve anything.

I think you’re on the right track with the BIOS updates. If it powers off within a minute after flashing, it sounds like the update didn't go through successfully. But if it keeps blinking for a while and then turns off, it likely means it worked. Just to clarify, have you also reseated the CPU and checked for any bent pins? That can sometimes cause these issues.
First off, have you thoroughly checked all your power connections? Make sure the CPU power connector at the top left of the motherboard is plugged in. You should have either a single or dual 8-pin connector there. Also, check the 24-pin connector for the motherboard. Don’t forget to ensure your GPU has the necessary power cables connected as well! Sometimes, these little details get overlooked.
