I would like you to set the BIOS to defaults and check for issue resolution. Please follow the steps mentioned below to load the BIOS to defaults.
Reboot the computer.
When prompted during POST, press the <F2> key to enter the setup screen.
On the System Setup screen, press the <F9> key.
Press the <Enter> key on Yes to Load Optimized Defaults and restart the computer.
If the above steps do not fix the issue. Please private message us the system tag and the region you are located so that I can check and assist you further. To send a private message, click on my name and send private message.
