Hi,

Specs:
  • CPU: AMD Ryzen 7 5800X 3.8 GHz 8-Core
  • GPU: Sapphire AMD Radeon RX 6800 XT Pulse 16Gb
  • Motherboard: Asus ROG STRIX X570-E GAMING ATX AM4 Motherboard (ASUS BIOS version 3001)
  • Hard drive: Kingston A2000 1 TB M.2-2280 NVME Solid State Drive
  • PSU: Corsair RM 750W 80+ Gold Certified Fully Modular ATX
  • Memory: Corsair Vengeance LPX 32 GB (2 x 16 GB) DDR4-3200 CL16
  • Case: Corsair 4000D Airflow ATX Mid Tower
  • CPU Cooler: Noctua NH-U14S
This is a PC I built almost 2 months ago. I had a defective motherboard B550-F Gaming at the begining that I had to switch for an X570-E Gaming. Since then, no issue at all. Stressed it with all sorts of new games with no problem (even my 50-hour time in Cyberpunk 2077 at Ultra was smooth)!

This morning, I turned on my PC, did random things like cleaning my Steam save files, played for almost an hour and read some web articles. No issue. Did not install anything. Turned it off. Then, about 3 hours later, I turned it on with a scary message at post: "The VGA card is not supported by EUFI driver" (https://postimg.cc/DW2CJCSG). I also notice 2 keyboards and 2 mice, which is not true..?

What I did, in order:
  1. Hard restart -> same screen;
  2. Turn off, disconnect-reconnected HDMI, turn on -> same screen;
  3. Went in BIOS (F1) and restart from there -> booted to Windows successfully, but slowly and screen was flickering. The taskbar was also all black and unclickable, but I could open folders on the desktop;
  4. Ctrl+Alt+Del to restart from there -> booted to Windows successfully, but with with "asusns.exe - Assert Failure" error message (https://postimg.cc/YhT0CVyX). However, everything seemed okay. I managed to open folders and start a Youtube video.
  5. Windows restart -> everything seems okay, back to normal.
  6. Tried to turn off and restart multiple times -> no issue so far.
I really don't understand what happened. Do I have to worry? Does somebody have any suggestions?

In Windows System Information, I see my BIOS mode is UEFI right now. My other PC (9? years old) is Legacy. I admit, I have absolutely no clues as to what I should be using. Please guide me.

Thanks.

Thanks for your reply. I don't have an ASUS keyboard. My keyboard is a Razer Blackwidow Ultimate. This makes me think however: some days ago, I disabled Razer Synapse at Windows startup as it randomly started to prompt a login screen. Can this really be relevant to my "VGA card not supported" problem?
