Hey Everyone, this is my system
CPU: AMD Ryzen 5 2600 (stock clocks)
RAM: 4 × 8 GB 3000 MHz
MB: MSI B450M PRO VDH PLUS:
STORAGE: 1 × 1 TB NVMe, couple of SSDs and HDDs
GPU: AMD RX 6700 XT
PSU: High Power Astro GD 850 watt
The PC worked perfectly fine until late last night, I was gaming and it was stable. No crashes or anything.
When I got home today, I tried to turn it on, but it didn't boot, and the motherboard debug LEDs showed a VGA error, while the monitor was completely black. I tested my GPU in a friend's system, and it worked perfectly fine. Even played Alan Wake 2 for a bit to make sure it's stable, and it was.
I took my friend's 6900 XT that is working fine and tested it in my system, which exhibited the same behaviour.
I also tried changing the GPU power cables with new ones, unused, from the PSU box, I tried using another GPU power out header on the PSU, I tried removing the CMOS battery, and reinstalling it after a few seconds, I tried shorting the BIOS reset using the motherboard jumper, I tried booting with one stick of ram in different slots, I tried removing all USB and other peripherals, none of which helped, I still get the VGA error. Two things I have not tried, is using a GPU without PCIE power cables and another power supply, which would perhaps rule out problems with my PSU.
Based on this, I suspect my motherboard to have [language]. Any ideas? What else can I do?
Thanks in advance.

What is the age of your PSU in this build?
MB: MSI B450M PRO VDH PLUS
Sorry, your motherboard lacks a BIOS Flashback button, so you can't restore the BIOS if it's corrupted. You might consider getting a CH341A BIOS programmer and flashing it, or check if another reliable PSU from a friend or neighbor could help revive the system.

The PSU is nearly 9 years old, but it's been four years past its warranty. The manufacturer's website states they offer 10-year warranties on newer models. That seems like a challenge, might there be another way? I suspect I won't be able to locate a BIOS programmer either. Also, I'm not sure what caused the issue after the PC started working normally again.

I checked my friend's confirmed power supply unit, but the issue persisted. Likely it's the motherboard.
