I use my computer almost everyday for low demanding tasks, mainly YouTube & it runs perfectly. Once every couple of weeks or so., I'll try and game.

Everytime I try to play, no matter the game, it crashes in the first 15 minutes or so. The PC doesn't crash, just the game. If I play the game for a few hours, this will eventually stop. However if I leave it for a week or so, then come back, the same thing happens again.

I mainly play Apex Legends. While on this my CPU is around 65% & my GPU is almost always at 99%.

I've tried lowering the graphics to lowest settings, but it doesn't help. Below are my specs:

i7-4790k
16GB ram
GTX 1070
700W Aerocool Integrator

I really don't know what to do. Do I need a new CPU? GPU? Any help would be appreciated

Thanks
 
Is Aerocool Integrator 700W 80+ right for my PC?

16GB ram - part number and/or link to it?
