My brand new gaming Computer crashes after playing games like far cry 5, fortnite, rust

[VatixOG]

Hello,
I just bought a 1 grand PC and it has pretty good specs but yet it still crashes when I play certian games, usually after 40mins or over an hour
the specs are as follows:
GPU: GTX 1060 6bg GDDR5
Processor: Intel Core i5 7600k
RAM: 16gb DDR4
SSD: 240gb
Sorry if not enough, im realitivly new to this, also I ahve looked into it and I dont think its overhewating as I watched the temperature and the max it went was 87 degrees celsious then I heard it might have something to do with ram but im not sure, please help ive been getting really stressed over this

Sorry if its in the wrong area btw

First, make sure you have space around the system so there is good ventilation. Then make sure all the fans spin. If you still have an issue and its new and you are a newbie, get help.

If I had just bought an expensive computer and it was behaving like yours, I would contact the technical support folks at the place the system was manufactured. Very often a bunch of new systems may be assembled with an incorrect driver or something.
