Specs:
AMD Ryzen 5 1400 Processor
Kingston Value DDR4 2400 Mhz 16GB
Kingston SSDNow UV400 240 GB 2.5" SSD OEM
Seagate Barracuda 1 TB 3.5" HDD
Cooler Master MasterBox 5T Midi Tower
Gainward GeForce GTX 1060
ASUS Prime B350M-A Socket AM4
Corsair VS550 550W PSU

There is no issue when I don't run games, but when I try to play games like Wildlands the PC crashes between 1-5 minutes depending on the graphics. I don't really know too much about PC seeing as I used to use a mac before this. I have tried to remove all display drivers and reinstalled the newest and original. I don't know what to do so any help from people with more knowledge than I would be much appreciated. Thanks, if you have any questions feel free to ask me, I will answer as quickly as I can.

1. I have not overclocked anything
2. I did a GPU stress test with amazing results, nothing seems to be wrong there. Also looked at the temp for the CPU when it crashed and it was only on 49 celsius.
3. I cant find anything on how old the PSU is sadly :(

Yes with both in high and low settings. It crashes anyway, but when I have low settings windowed it runs a bit longer than in fullscreen with high setting I think. Might just be me though, I'm not 100% sure about it.

The screen just goes black, my monitor doesn't pick up any signals neither does the mouse and keyboard. I have to turn the power on and off then everything works fine again.
