Sometimes my PC crashes unexpectedly while gaming

[Jawad14]

Since I've updated my ASUS Prime x470-pro motherboard's BIOS to the latest version from asus.com , I started facing this weird issue. Sometimes when I play League of Legends and the game is either ended on a defeat or victory, the whole computer just freezes and becomes unresponsive at all, I can't tab out and can't even do ALT+F4 or even CTRL+ALT+DEL , so I just force shutdown the PC by holding the power button for about 4 or 5 seconds. I'm using a Ryzen 7 2700x with 16Gb RAM G.Skill Trident Z RGB 3200Mhz. Since I updated the BIOS, I realized something weird in the Task Manager, on the page of "Memory". I've attached a picture of it. I can't see the RAM's speed, and hardware reserved memory is ZERO, in-which I suppose before updating the BIOS it had some value instead of ZERO. and there seems like a couple of chunks of information that was on that page has suddenly disappeared after the BIOS update. So am not sure about whats really happening right now and would like some recommendations on what to do regarding this problem, cuz until now I've force-shutdown-ed my PC about 5 times because of this issue.

first of all is anything overclocked or undervolted?

What are you powering the system with? Your issues sound like a broken power supply/board or drivers

I have nothing overclocked except for the GPU overclocked by using a preset from ASUS's own app which is "GPU Tweak", in-which am on OC mode. Never touched anything regarding "undervolted" and didn't even mess with the ratios in BIOS, but I have the "Performance" preset selected in the BIOS instead of the "Normal" one.

I'm powering it with a EVGA SuperNova 750W G3 , but I haven't plugged the PSU directly into the wall. But instead, I have it plugged into an extension from Terminator that can withstand 3000W, in-which it contains 4 plugs, and I use the first one for the PC, second for the Monitor which is a ASUS PG279Q, third for some RGB lights, and fourth for an LED clock.

The G3 are known to have OTP and OPP issues and are genuinely best avoided.

But this problem never happened until I updated the BIOS. Maybe if I downgrade my BIOS the problem's gonna be solved?
