Dell Inspiron 15 7000 Gaming Laptop Shutting Down in Games

Apr 30, 2018
Hello all,

I have a Dell Inspiron 15 7000 Gaming Laptop with 1050 Ti, and I have a problem.
When I try to play games, such as COD Advanced Warfare, Fortnite etc. my laptop just switches off automatically. I've tried a few things such as:

-Monitor temps using MSI Afterburner: Temperature for CPU is around 70-85 C then crashes, whilst GPU is like 10 C less than CPU. (I've done no overclocking at all)
-Clean the fans, no dust clog up.

For some reason, whilst playing CS GO, it never crashes (Probably because its a pretty old game :/ )

Wondering if anyone could point me in the right direction to resolve my problem, can't even string two games of FN without it crashing and shutting down.

Edit: Forgot to mention laptop is 6 months old, and it wasn't like this until like January this year.
