[itzricardob]

I have done everything when I first booted pc before all this I had a purple pixelated screen on Dell screen it booted to windows then fixed it self and kept switching off whilst in a game menu it played rocket league amazing but rust and apex legends would crash, I launched apex and it turned off and didn't turn back on I have took ram out and made sure it beeped and it did so motherboard is ok I have cleared CMOS reseated CPU tried original Dell PSU and used motherboard VGA still nothing I have gone ahead and refunded my 500w PSU from amazon I got for my Rx 570 and bought a 600w I hope this works

Run a GPU benchmark like furmark, then an CPU benchmark, see if the system is stable. 

 

 

My theory 

 

It seems like the GPU takes a bit of power from the mobo, due to the Mobo quality, that's whats causing the crash. more GFX intensive  Games will use more power. get a card like the 750TI, they use almost no power.
