Question Black screen after attempting to flash bios

[bdelvillano]

So, i go to flash my BIOS with a flash drive, I go into my BIOS and hit "M-Flash", and nothing happens. I am stuck on a black screen so i restart my computer, keep in mind i didn't even start updating anything. And when I go to turn my computer back on, it doesnt post. My keyboard or mouse dont light up, and its just a black screen. All i did was hit "M-flash". I didn't even start updating anything yet. There are no red lights flashing on my motherboard, and I have tried resetting the BIOS by hitting the button on my motherboard. Here are my specs:
MSI B450 Tomahawk
Ryzen 7 3700x
Corsair tx850m
GTX 1080 Ti
32gb 3200mhz trident Z memory

Edit: Now my computer wont even turn on.

What procedure did you follow?

Where did you get the flashdrive?

I restarted my computer, went into the bios, hit m-flash, and then my computer went to a black screen and never recovered. i tried resetting the cmos multiple times and my computer still wont turn on. I honestly think my motherboard simply died so i am probably going to send it back.
