I need help to fix my computer

[Julixfc]

one day i was just playing pubg and then my computer just crashed.
i think the problem is that my power supply is not good enough, or my cpu is overheating.

PC Spec:
Fractal G Focus Min
500W SilverStone 50 plus Gold PowerSupply
Zotac 1050 Ti OC Graphic card
1TB 250SDD Storage
Amd Ryzen 3 1300x CPU

When crashes the monitor turns black, but the computer is still on but doesn't respond.

need much more info. do you overclock? resolution? remember pubg is an online game dependent on ping. there is no such thing as "50 plus" ....silverstone is not that great.

i underclocked my graphics card, and my ping is normal, and i replaced the thermal paste
