msi b650 gaming plus wifi bios ipdate not working (white screen)

hi, i just assembled my new pc and decided to update bios. i plugged my pendrive into flash usb socket and downloaded newest drivers from official msi page, unzipped files and transfered them to (clear) usb and disconnected it (by right clicking on it) then i restarted my pc and entered bios, chose flash option and it said that my pc will reboot to enter flash mode, it did restart and there was screen "entering flash mode" then my screen went white, i gave it like half an hour and nothing changed, so i restarted it and did everything again but the result remained- white screen and nothing happening. am i doing something wrong?
