Bios update , after black screen MPG B550 GAMING PLUS

[cobralamoula15c302e6]

Hello, I just updated my BIOS. I did everything correctly (following a tutorial), but once the update was finished, my computer restarted and now my screens won't connect; I can't do anything. Could someone help me?

Does the debug LED stuck on specific LED? Have you tried clear CMOS?
Do you have a iGPU to try? Perhaps list the system config.

Yes, check the EZ Debug LEDs on the board. When you don't get a picture, then looking which LED stays on will give an important clue.
Also, we need to know the rest of your hardware.

Here the little led in withe and nothing else, I try clear CMOS and nothing.

Ok, VGA LED. Now please your list of hardware, so we can get to the bottom of this. CPU model, GPU model...

Hmm, just a Bronze-rated PSU with such a GPU, I would've for sure gone for a Gold-rated one already which ticks all the boxes. But the PSU normally shouldn't be the cause of the VGA LED. What's the SSD model?

Which BIOS did you flash, the latest, 7C56v1L? Do you remember which version you had before?

Since your board has the Flash BIOS Button, try to re-flash the BIOS to the latest version with that, or you could also try the 7C56v1K version.

The procedure:
1. Download the latest BIOS from the MSI support site for your board and extract it.
2. Take a USB stick and format it to FAT32 (it's best for it to have a size of 32 GB or less). You can also try Rufus for formatting, as FAT32 non-bootable.
3. Rename the extracted (!) BIOS file to MSI.ROM and save it to the root of your USB flash drive / USB stick (not in a subfolder).
4. Plug the USB flash drive / USB stick that contains the MSI.ROM file into the marked Flash BIOS Port (!) on the rear I/O panel.
5. With the PC off (!), press the Flash BIOS Button, and the LED should start flashing for about 5-8 minutes and then the board reboots.

Anything drastically different (under a minute of flashing, or over 10 minutes of flashing) and the flashing didn't work, so you can abort and try with a different USB stick (sometimes the board can be very picky as to which USB drive it will accept). After ten minutes it will never finish.

This is the problem I dont remember which version I have before, and for my SSD it’s

CRUCIAL E100​

Ok, a cheap budget SSD, DRAM-less, using QLC NAND, and consequently very low TBW value. On the plus side, it's from Crucial. Sometimes, a problematic SSD can also trigger the VGA LED, but my gut feeling is that the SSD is not involved here. Still, you could take it out for a test if you want. It's always good to rule things out completely by leaving them out, wherever possible.

But the best way forward would probably be to flash the BIOS again using the button. First perhaps the latest version again, then you can also try 7C56v1K, and older versions as well. Not too old of course, the maximum I would go back to is the 7C56v1B.
