usually it dont take long, probably 10-20 mins long for the whole operation of accessing the BIOS, the flashing of the BIOS and the POST flash boot up. but for an hour? are you sure you got the right bios for your motherboard model? coz you might have bricked your motherboard. edit: you got your bios from MSI center? it's better you downloaded the rom from your motherboard product page, format your USB to fat32, unzip the rom files to the USB and enter bios to perform the flash. 3rd party apps, initiating from the desktop/OS level might bring problems.

r/pcmasterrace on Reddit: How long does a BIOS update take ? Should I be worried about the black screen
August 10, 2025 -
So... My PC was having some issues, and windows 10 is getting unsupported in a few months.
So I got all my sensitive data out, reset the windows 10, updated it, got MSI center, and figured out a BIOS update couldn't hurt.
Buuuuut it's been an hour, my screen still doesn't give me any feedback.
I just have a single rRGB light on the motherboard lit up rn, behing the graphics card. So... What do I do ? Should I be worried?

January 19, 2022 -
I have Asus X-570 E-Gaming. The mobo was showing green Q-LED today, I came to know it's because of failed boot. So, I'm updating the BIOS(firmware or host boot software). The size of the flash file is 32 MiB and the flash drive used is 2.0 one. It's been 22 min now and the green LED(which indicates the BIOS is being flashed) still hasn't gone off, and now I'm worried. What to do?
For reference:
Asus X570 E-Gaming, GSkill RipJaws 32 GiB DDR4 @ 3200MHz, Ryzen 5 3600, Samsung 980 Pro PCIe4 SSD, DeepCool 850W PSU, Zotac RTX 3090 Trinity

Ooof. I hope it finishes for you. It should reboot after it is done by itself. I hope it comes back up one way or the other. Firmware probably wouldn't fix a boot failure that happens out of the blue that clearing the CMOS wouldn't fix. The good news is that the board has a recovery firmware image normally (Q-LED code F0 through F4 for the BIOS attempting to use the recovery image). The LED you are talking is the Flashback LED (in between the Flashback button and the USB port) or the Q-LED (which displays the code and is located below the bottom most long PCIE x16 slot)? What I hope is happening is that you didn't unzip the firmware on the USB and it hasn't actually started flashing the BIOS. What you are supposed to do is unzip the file and either run the BIOSRenamer.exe file OR manually rename the .cap file to SX570EG.CAP on your USB stick. You then put your USB stick into the Flashback USB port (the very bottom one) and then press and hold the Flashback button for 3 seconds. Once the LED flashes 3 times and then starts flashing the BIOS. If you didn't rename the file, then I'd probably power it off since it has been roughly an hour, rename the file, clear the CMOS which will reset BIOS settings to the defaults and try to flash again. Though flashing the CMOS is optional and isn't always required, I definitely recommend it. You can clear the CMOS by completely powering down the PC, unplugging it and waiting about 10 seconds. All of the LED's should be off at this point and capacitors discharge. Now locate the CLRTC jumper pins (should be just 2 pins) located to the right of the bottom long PCIE x16 slot, left of the SATA connectors, Below the M.2 slot and above the RGB_HEAD2 pins. Apparently ASUS didn't make this a 3 pin with a jumper just sitting there for you to use, so you'll have to use something like a screw driver and lightly touch it between both pins at the same time (no pressure needed, it just needs to touch both) for a second. Now remove the screw driver and plug the cord back in try to do the Flashback process again. There is a CMOS battery, after powering down, that you can pop out to do the same thing but I wouldn't recommend it since the cradles can sometimes break easily when trying to get the battery out and the only way to fix that is to re-solder it back into place. Plus it is between the top two PCIE x16 slots and probably inconveniently under your GPU. IF your BIOS flashes and comes back up, it may still fail to boot due to the original problem. If that happens, find your Q-LED display (not the Flashback LED) and check the Q-Code table in the appendix of your motherboard manual to figure out why it is failing POST. Hopefully it is just 50 up to 55 and you just need to reseat your RAM sticks. You can also follow the POST process as it does its different test by watching the codes progress. If it was E8 thru EB, then the CMOS reset should have fixed that anyway. Good luck!

3-5 minutes in my experience. I've also had a BIOS flash seem like it was taking way too long. And it wasn't going to finish. It wouldn't boot. So I did clear CMOS and retried the flash. It worked the 2nd time. Gigabyte B550 Aorus Pro for reference.

I have a GIGABYTE B550 Vision D-P it's been almost a year since l've update bios. So l've decided to update it. Now I'm in a black screen l've waited for about 2 hours. Should I turn off my pc and turn back on or should I wait it out. Any suggestions?

2 hours is excessive. Most take 3-10 minutes depending, usually Intel boards take longer than AMD due to updating the ME firmware. Did you do it with the flashback or through the bios interface?

should only take at least 5 minutes or shorter - waiting for more than 15 minutes is too long - i guess you have no option but to power off and turn back on, see if update was successful,
