[SOLVED] black screen after flashing bios

[fuukakun]

i have a msi b450 gaming plus motherboard. i tried flowing the boss through the flashback+ method so i connected the usb and then pressed the button. after the flashback led flashed a few times it stopped and then nothing happened. it's supposed to restart but it's just starting there with everything on and the screen is just black. i tried pressing the power and the restart buttons but nothing happened so i turned the pcu off. when i turned it on and pressed the power button the mb turns on and the fans start turning but the screen is still black. i tried the clear cmos jumper and removing the battery. finally i tired reflashing the bios with an older version but it didn't work. I'm really lost please help

Have you renamed the BIOS file? USB drive FAT32 formatted?
Before updating: Please download the latest BIOS file that matches your motherboard model from MSI® website and rename the BIOS file to MSI.ROM. And then, save the MSI.ROM file to the root of USB flash drive. Important Only the FAT32 format USB flash drive supports updating BIOS by Flash BIOS Button. 1. Connect power supply to CPU_PWR1 and ATX_PWR1. (No other components are necessary but power supply.) 2. Plug the USB flash drive that contains the MSI.ROM file into the Flash BIOS Port on rear I/O panel. 3. Press the Flash BIOS Button to flash BIOS, and the LED next to the button starts flashing. 4. After the flashing BIOS process is 100% completed, the LED would be off simultaneously

also after following this https://forum-en.msi.com/index.php?topic=269702.0
the pc rebooted by itself in the end of the process but the screen is still black (along with the six copies i put another one named MSI.ROM i also did this using flashback+ method as i can't get into the bios

try booting with 1 stick of ram?
which port on the gpu are you using to connect to the monitor?
does it sound like it turn on at all?

i tried without any ram and it didn't work will try with one stick in the morning I'm using the hdmi port and no there's absolutely no response from the screen on startup though the leds in the mb turn on normally

i tried with one ram in the morning and apparently it fixed itself. it might have been because of the one ram or maybe because the pcu was off during the night
