Last night I turned off my PC as usual, nothing strange happened, this morning I went to turn on the PC and it didn't start, not even the RGB, not anything. Then I noticed a green light blinking on the back, it was the bios flbk, I didn't know what it was until now that I researched it. Tried everything to fix it, removed de CMOS, used a screwdriver to turn it on, checked the button itself, I tried to update the bios with a flashdrive, unplugged all the cables from the back, move it to my table and I connected the USB on the bios port, and I let it run for several minutes, but after 30 minutes I thought my MB was dead, so I just let it there to do some other things, came back 2 hours later, pressed the power button, and it booted, I got excited, turn off the pc again, put it back at my desk, plugged everything back, and now it doesn't start again, I don't know whats wrong, its been another 30 minutes, and it's still blinking, am I doing something wrong? And how did this happen if I never have messed with the bios or this button?

Its an Asus prime x670-P WIFI

I flashed the bios with just the power supply and nothing else first and it seemed to go fine - blinked for a while and then stopped. I then put the rest of my build together and after turning on the power supply the BIOS flashback led won't stop blinking. I plugged the USB back in and pressed the button again and it blinked quickly and cycles between blinking quickly and slowly. The system will not post.

Hello all!

Yesterday overnight my PC suddenly stopped booting and the green BIOS Flashback LED in the back is blinking the whole time (I haven't pressed it). The RGB lights on the Mainboard are still on though, so it is getting power.

Cleared the CMOS then it booted up with all fans spinning but there was no display on the monitor and then after wanting to restart the system, it went back to the blinking green BIOS Flashback led state.

Then I tried updating the BIOS via Flashback but it just kept blinking green like before, seems like it just gets overwritten by whatever is going on.

Sometimes when pressing the BIOS Flashback button in the back, the system starts randomly which I do not understand to be honest but also with no display and the red Q-LED lights up on the Mainboard, which would hint at a CPU issue?

I'm really lost to be honest and have no idea what else I could try apart from getting a new Mainboard and/or CPU possibly.

Hey everyone, I built my first PC yesterday and wanted to update the BIOS. I did it exactly as described on the Asus website. Update to USB, renamed the file, plugged it in the back and pressed the flashback button until it blinked. I have a Tuf Gaming b650 plus motherboard. Then I checked from time to time, but the light was still on, so I went to bed, and this morning it's still on. In the Asus video, they say I shouldn't turn on the PC while the light is on.

I don't know what to do. Just leave it or is there something I can do?

Thanks in advance.

Trying to update the BIOS, watched the tutorial on the ASUS website. LED is supposed to turn off when update is finished, but it been on for over an hour. Wondering if it usually takes this long. Video said not to power off computer, remove flash drive, or press reset cmos button.
