Hello everyone. new builder here. just today I finally took the plunge and assembled my PC after having my parts waiting to be used for a while (in their packaging and anti-static bags, don't worry). and once everything was assembled, I tried to turn it on but only a single RGB strip on my motherboard actually turned on, and the green BIOS light was flashing. A friend and I troubleshot it for about 2 hours, I tried a BIOS update because my board needed a later version to work with my CPU, and yet after trying a CMOS clear. making sure all the pins were in place, it's still in the same state of single RGB light on and the BIOS light flashing, any ideas on what's causing it?
SPECS
ASUS TUF GAMING B550 -PLUS WIFI II
AMD Ryzen 5600X
AMD Radeon 6600 (planning on upgrading but have no need to currently)
32GB Kingston FURY 3600MHZ
NO HDD, single SSD that I plan to supplement with another one later.
Be quiet! system power 9 PSU

Did you update the BIOS, and if yes, which version?
What is the primary storage drive?
Have you attempted a clean installation?
Does it launch properly?
The 5600x is compatible with all BIOS versions.
I don't get why you began altering the BIOS settings.

Welcome to the forums, newcomer!
Please keep it quiet! system power 9 PSU
https://www.bequiet.com/en/powersupply/s...wer-9/1274
What series is this for the PSU? What is the wattage of your unit?
I attempted a BIOS update because my board required a newer version to work with my CPU.
Did you follow the steps in the guide you mentioned?

To flash your BIOS using the BIOS FlashBack button on the rear? Speaking of the button, did you install the board into the chassis correctly without the BIOS button being pressed unnecessarily?
Hang on,

Are you certain you have the correct motherboard name? I see TUF Gaming on the VRM heatsink but I can’t find a support page for an

and yet after trying a CMOS clear
Can you guide us through the process of clearing the CMOS?

Hello, thank you for your kind words. This marks a refreshing break from the usual challenges.
Regarding the PSU typo, it's actually the 600 watt CM series; that should resolve the confusion.
I followed the steps similar to the YouTube tutorial you mentioned, and the flashback button is correctly positioned—it wasn’t obstructed by the side panel cover. I’ll include more images for clarity.
I’m confident about the model name, here’s the motherboard I used:
https://www.asus.com/motherboards-c..._b...US-WIFI-II
I cleared the CMOS as I recall doing it on my cousin’s system when he guided me through. On ASUS boards, there’s a small flap you lift to release the CMOS battery. I first unplugged the computer (ensuring it was off), then lifted the flap and let the battery fall out. After waiting five minutes for safety, I reinserted it, reconnected the power cable, and flipped the PSU switch again—no changes occurred.
Additionally, to explain how I performed a backflash, I used a separate laptop and downloaded the BIOS file for my motherboard from the official ASUS site. After removing an old USB stick and reformatting it to FAT32, I extracted the file, followed the BIOSRenamer instructions, and transferred the updated file onto the USB drive. I connected the USB to the BIOS slot on the side panel after turning the PC on, held the flashback button for about four seconds, and then released it. When the BIOS indicator stopped flashing, I removed the stick, turned the PSU power switch on and off, and waited to see if my system would boot normally—unfortunately, it didn’t.
The BIOS file used is listed below.

I chose to jump the motherboard using a screwdriver, but it kept showing some stubborn debug lights. After removing the board from its case and reattaching everything, it functioned properly once I switched the VGA cables. The PC now works correctly with the case power switch, and I plan to install the OS and drivers soon.
