[SOLVED] My PC randomly crashing especially while playing games

[nestera]

Can anyone please help me detect the culprit in my PC random crashes.

Crash Scenario is PC crashing while gaming or even in the lobby of the game. During the crash the monitor will turn off with no display and signal at all then the GPU will continue reading while the GPU Fan and Case Fan will have a high RPM. This is happening while the CPU, RAM, GPU, Fans and RGBs are still running.

The only way and button that functions are the reset button and hold press of the power button.

RIG:
Ryzen 5 3400G
Gigabyte B450i Aorus Pro Wifi
Gigabyte GTX 1650 Super Windforce OC edition but not Overclocked via Afterburner
2x8GB TForce @ 3200mhz RAM
480GB NVME
450w Corsair CV450 PSU
Display Port Cable in a 60hz Monitor
Updated NVIDIA Driver
Windows 10

AVG Temperature while playing:
CPU: 47-50c
GPU: 66-71c

Could be the PSU if it happens mostly in games when PC is under most stress.
3 ways to test PSU

the paper clip method - https://forums.tomshardware.com/threads/what-is-the-paperclip-method-of-testing-a-psu.1336402/
or multimeter, best way as you can test under load
or in the BIOS to check the +3.3V, +5V, and +12V. - https://www.lifewire.com/power-supply-voltage-tolerances-2624583

I assume windows just shows event 41 (63) meaning it doesn't know.
