I just built a new PC, but I'm having trouble getting it to display anything. After some troubleshooting, I was advised to update the BIOS on my ASUS PRIME B650-PLUS WIFI motherboard. I downloaded the BIOS files from the official ASUS site, formatted a USB drive to FAT32, and used a renamer tool to rename the .CAP file to PB650PS.CAP. I plugged the USB into the Flashback slot and pressed the button until it flashed three times, but the green light remains on, which seems to indicate a problem. Could I possibly be using the wrong BIOS file for my motherboard? Did I maybe use the wrong USB slot? Any guidance would be appreciated!

Looks like you might be using the wrong BIOS file. There’s a specific one for your WiFi version. Double-check with the link you shared—make sure you're using the file designated for the WiFi model!
Hey! Just checking, did you unzip the BIOS files or just copy them as they were? You might want to ensure you're following the steps in the official guide, as it has specific instructions for using the Flashback feature. Here’s a link to the guide if it helps!
Yes, I unzipped the folder first and used the renamer tool, then copied the renamed .CAP file over to the drive.
Are you absolutely sure that's the correct motherboard model? There's a version of your board that has WiFi and one that doesn't. Make sure you’re using the right BIOS file for the PRIME B650-PLUS WIFI by checking this link. You might need a different file for the WiFi model!
Make sure the BIOS file is in the root directory of the USB drive and not inside a folder. Also, when using the Flashback button, you should press and hold it for about 5 seconds, then release it. The green light indicates an error, and it should be flashing during the update process, which might take 5 to 15 minutes. If you're using the wrong BIOS, that's likely your issue.
Thanks for the tip! I will check that out.
