[SOLVED] PC shuts down during game loading screens ?

[IbraK]

Hello everyone,
I recently built a computer and i'm having problems during gaming sessions.
When i play a game with too many loading screens my pc just shuts off. I'm playing dragon age inquisition at the moment and this happens frequently during fast travel and such, thing is i played red dead redemption 2 and cyberpunk 2077 and i didn't have any problems cause both games don't have rely so much on loading screens.
I guess it could be something with the HDD or SSD? I already made some tests to see if there are any problems with both my HDD and SDD and it appears to be ok, same thing with CPU and GPU.
Here are my specs:
Motherboard: Aorus X570 Pro
CPU: Ryzen 3900X
GPU: 1660 TI
HDD: Seagate Barracuda 2TB
SSD: Kingston 480GB
Ram: 2x Hyperx Fury 8Gb 3200 Mhz DDR4
PSU: EVGA 750 BQ
For cooling i use:
Noctua NH-D15
3x Noctua NF-F12 PWM

My PSU and SSD are the oldest parts in this setup, i'm guessing 2 to 3 years old.
Yea i know my cpu is so much powerful than my gpu, thats cause of my job and cause i intended to upgrade to some better model, but the gpu market is kinda messed up right now.
Any help would be appreciated.

I would suspect the PSU as the cause

If you cannot test the PSU I would also check your RAM and check the life of your SSD. Check event viewer or reliability history for critical errors.

Do you have a multi-meter and know how to use it? Or have a family member or friend who does?

Not a full test as the PSU is not under load.

However, any voltages out of tolerance would make the PSU quite suspect.
