I just updated the BIOS on my ASUS ROG Strix Z370-F Gaming .Everything went fine during the BIOS update.but when the loading bar was at 100% my computer restarted with no screen output and all LEDs and components such as fans are working.I also refresh my cmos I try both method pulling jumper or removing battery but nothing work .
 
Solution

When you boot up, each LED will turn on, then turn off if the device is O.K. If the device has a problem it's LED will stay on. Does one of the LED's stay lit up?

1. Have you double checked the RAM to make sure it is pushed all the way down in it's slot, at both ends?
2. Is this a new build or has you been using this computer before the BIOS update?

1.yes I double check my ram ,ram fit perfectly in slot and I also buy new ram ..
2.Yes this is my first and new build my Pc run perfectly I installed windows 10 pro everything work fine but i was suffering blue screen of death [BSOD] error issues I made a mistake I thought it was bios problem so decided to update my bios after update bios there is no display on my screen.
 

If the progress bar reached 100% during the BIOS update and rebooted on it's own, the BIOS should be fine.
What is the model name and number of the RAM you are using?

Ram :
Corsair Vengeance® LPX 8GB (1x8GB) DDR4 DRAM 2400MHz Memory Kit - Black (CMK8GX4M1A2400C16)

Your single stick of RAM should be located in memory slot "DIMM_A2". The slot closest to the 24-pin power connector.
