Question My PC crashes randomly in some games!

[T0AKS]

Hey! I have a issue with my half year old PC. When I start my Witcher 3, PUBG my screen just goes black and my GPU's fans go very loud and fast.

My specs:

MSI Geforce GTX 1060 6GB
Ryzen 5 1600x
Hyperx 8gb ram 2666MHz
550w PSU
1TB HDD
256gb SSD

My GPU is bought used, other parts are all new.

Can somebody help and give advice what's wrong?

My psu is Mars gaming MPII 550
