Hey folks, I'm having some trouble with my new PC build and could really use your advice. I've got a Gigabyte B850 AORUS Elite WIFI7 motherboard, a Ryzen 9 9900X CPU, Corsair Vengeance DDR5 RAM, and some Antec C5 ARGB case fans. Right now, my system won't pass the POST check, and none of the RGB lighting on my fans or AIO cooler is lighting up. The DRAM debug LED isn't showing any errors, which makes me think the memory is fine. I've already tried reseating the RAM in the right slots (A2/B2) and even removed the GPU to keep things simple, but no luck so far. ChatGPT suggested doing a Q-Flash BIOS update to fix potential compatibility issues and get the RGB working, but I can't seem to get the flashing process to start. I've formatted a USB with the latest BIOS as FAT32, renamed it correctly, and plugged it into the Q-Flash Plus port, but when I hold the Q-Flash Plus button, all I get is a cycle of powering on and off. Any tips on triggering the Q-Flash, or other ways to get this RGB and my system up and running?

Before messing with the BIOS update, try clearing the CMOS. Sometimes that can help reset the hardware issue causing your PC not to boot. Just make sure to follow the instructions in the motherboard manual for it!
You might want to try using a different USB drive, especially one that's 32GB or smaller. Some motherboards can be picky about which USBs work for BIOS updates, and newer models sometimes struggle with larger drives.
Thanks! I’ll see if I have an older USB to test with.

Got it, I'll definitely give that a try!
