Hello, @jack01 

"Last week I started having issues with the board."
>> Could you please provide more details on the specific problems you encountered or any software or hardware changes that preceded the issue of being unable to boot with the VGA indicator light on? For instance, did you change the GPU or update the BIOS?
When the VGA indicator light is on, do the RGB lights and fans on the motherboard activate? 

Considering your current CPU supports integrated graphics, we suggest removing the GPU and connecting the monitor to the rear panel port on the ROG STRIX B450-F GAMING to confirm.
Please follow the guidance outlined in [Motherboard] ASUS motherboard troubleshooting via Q-LED indicators for troubleshooting steps.
Meanwhile, we suggest you refer to [Motherboard] Troubleshooting - No Power/No Boot/No Display and test with minimal components to isolate the possible cause.

Thank you.

Thanks for the response

The issue started when I did the graphic driver update  using Asus utility.

When the VGA light is on the fan activate(they are on)  RGB light on

I do not have GPU in the system,  I am using the integrated graphic on CPU.

Unfortunately because of no display, I cannot access the bios or anything on computer

Hello, @jack01 

Based on your description, we recommend installing a GPU to further verify if the driver version is causing any abnormalities or cross-testing with a different CPU.
If you don't have the necessary hardware for cross-test, we suggest sending the motherboard to repair for further inspection.

Thank you.
