Also double check the CPU power connectors and make sure they are plugged in all the way and also plugged in all the way on the PSU end.

Double also, find your CPU on this list: https://www.msi.com/Motherboard/MPG-B550-GAMING-EDGE-WIFI/support#cpu and update the BIOS using the BIOS flash button following the instructions on the page. Fat32 formatted USB stick, rename file MSI.ROM, make sure its in the root directory of the drive with nothing else (formatting should take care of that) and press the button (hopefully your board has it). The red light should flash for about 3-5 mins or so and the board will autoboot when it's done.
Edit: just checked, it does have flashback, make sure its in the USB port directly under the flash button on the back of the mobo

does it matter if i have ram and the cpu plug in?
Yes, you need 3 things for the board to POST into the BIOS. CPU, RAM, GPU. POST sequence checks each one and then boots. You should leave the CPU and RAM in as well as the GPU so you will know if it works. Once you successfully get into BIOS, use the Windows Media Creation tool on the USB stick and choose the USB drive as the bootable drive in the boot priority list, then hit F10, this will bring you to the windows installation screen. If you don't have a laptop or something I'd ask a friend if you can use their PC for about 5 mins to create the BIOS flash drive, and use another USB drive to create the windows media installation using the Windows Media Installation Tool.

they are
ill try to download the BIOS update but i havent even download windows on the pc
Not for Bios update some times a nude board is easier

Read directios and watch teh Vid it will help

Some directions for you



FOR BIOS FLASHBACK

Following Directions are for windows based OS

Right Click on the Downloaded Bios Zip File, select properties if you see the message this file is blocked by windows tick the box to unblock and click OK.

When in windows File Explorer make sure that you select the View tab and Tick the box Show Hidden Files and File Name Extensions.

Extract the BIOS file from the Downloaded ZIP file Open the folder it was extracted to.

Right click on the BIOS file, select copy and then paste it into a 32GB or smaller USB drive drive Formatted to FAT32.

When in Windows File Explorer make sure that you select the View Tab and Tick the box Show Hidden Files and File Name Extension.

Now rename the BIOS file to MSI.ROM

There should be no other files or folders on the USB drive, just the BIOS file you have renamed to MSI.ROM


FlashBack can be used on a fully assembled PC even if CPU is one of the new 5xxx series.

PC must be turned off for BIOS Flashback to be started do not turn on your PC the Bios Flashback will do it for you




Plug the USB Drive in to the USB port just below the Bios Button,

Do not touch any Jumpers on the Motherboard

Push the FlashBack button and then release it,

About 5 seconds later a led just above the USB port will start to flash, after 15 seconds of so the speed of the flashing light will double this is the writing to the BIOS period.

Once done writing to the it will stop flashing and PSU will turn off

For 16MB BIOS it will take about 4 to 5 minutes, and flashing stops.

For 32MB BIOS it will take 6 to 7 minutes, and flashing stops.

People have said that it may turn back on if so just turn off and unplug the PSU.

And Bios should be flashed.

Failed BIOS flashback is one of three way

One- it never stops flashing
Two- Solid LED no flash and stays on till you power of PC
Three- it flashes four of 5 times and then stops


Successful it will flash for about 15 to 20 seconds it will then it will start flash quicker for 4 to 6 minutes and then turn off.

The good thing about having it assembled is that it will just boot up and you're good to go if the update is successful, but yeah if you haven't actually installed the mobo in the case or locked down the GPU, I can see that.

Also if it's the CPU DEBUG light did you update the BIOS already using the flashback button and USB slot? You're pretty much just spinning your wheels until you update the BIOS at this point. Also you can unplug the cooler from the board, it won't hurt to just try to boot in for now.

Also should I update the BIOS using the flashback bottom with all the component plug in? Because I saw that you should do it without anything on the motherboard

You can do it with everything plugged in, it won't hurt anything.

Also if it doesn't work re-format the flash drive in Fat32 and try again, if that doesn't work get a new flash drive. It likes the Kingston drives, it's SUPER picky about what Flash drives it will accept, if it's an old one it most likely won't work.
