New graphics card powers down computer in every game

I am having big problems with my new 8gb Sapphire RX 480. Every game I play eventually crashes and my computer turns off and restarts.

I have tried DDU to uninstall all AMD related software and also tried using older drivers. First off can someone please tell me if anything from the

GPU-Z data looks out of place.



Here is a link to the exact model of my PC - HP ENVY 700-311na Desktop PC Product Specifications | HP® Customer Support

There is no official BIOS listed under Windows 10 but there is for 8.1

I think I have just about tried everything at this stage and from what I have read online this is a well know problem
