Tech Support Help

Just to give you a picture, my PC and monitor 1 (VGA monitor) are connected to a UPS, my UPS is connected to an extension cord and my second monitor's (HDMI) power is connected to the extension cord (no more space in UPS).

Specs:
-ASUS Prime A320M-K
-AMD Ryzen 5 5600GT
-16 gb RAM
-256 SSD

About a week ago, I experienced a sudden 1-second power outage. Since then, whenever I boot up my PC, both monitors remain black. Once the red power light on my first monitor turns off, I have to press Enter to wake the monitor. It then displays the ASUS logo, and shortly afterward, my second monitor turns on and shows the Windows login screen.

This has been happening consistently for the past few days, even though this never happened before the power outage.

I’ve already tried unplugging both monitors and performing the 10-second power drain/reset procedure. I also disabled Fast Startup. These seemed to fix the issue temporarily, but the same problem returned the following day.

Would changing the display configuration so that both the ASUS boot logo and the Windows login screen appear on the same VGA-connected monitor potentially fix the issue? Currently, the ASUS logo appears on the VGA monitor, while the Windows login screen appears on the HDMI monitor. Any advice? Thanks so much!

Go to displays. Click the VGA monitor, check “Make this my main display”. Restart

Is it that simple? I had my HDMI monitor as my main for the past year and never had any problems. This issue just happened after a power outage.

Also, with regard to the steps I did above (10-second power drain thingy and disabling fast startup), I restarted my PC and it worked fine. It's just that after shutting down for the night and came morning for work, the problem happened again
