I went to flash my bios, so I downloaded the newest beta file from msi 7C56vAA1(Beta version).

I went into the bios -> clicked Mflash -> clicked yes on prompt for reboot -> was provided a lit black screen on both monitors and nothing else. From here I rebooted, and now I only get the black screen. I've tried all 4 ports on my gpu, the hdmi port on the motherboard itself, reseated the ram, removed the cmos battery, and it provides the same outcome every time.

I then tried to flash the bios via the button in the back (with the 7C56vA9 file), but when I put the usb with the file into the flash usb slot and click it, while powered off but with power, it doesn't turn the pc on or as far as I'm aware ready the new bios file.

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.
