I've been playing Battlefield 1 for a longer period of time and it didn't cause any problems. Then I launched CS:GO, League of Legends, Titanfall 2, GTA 5... It shut down after 5 min of playing it. I don't think its a problem in graphics card because BF 1 is hard on it, then I tested my temps and they were ok, I really have no idea what the problem is if someone can help I would appreciate the help.

Graphics card: Nvidia Gtx 970
Ram: 16 gb ddr3
Pcu: 670 W
Motherboard: Z90-a
Cpu: i5 4690

Ofcourse not, when I ran a game individually after maybe a minute, even less sometimes, my PC would restart.

It has to be heat related. How many case fans do you have, do not count the fan in the power supply, or the one for the video card. If you do not have a fan for the video card, you might need to think about placing one across the card.

I thought of that as well, and I've tested my temps in all of those... They were fine even better than I thought. Even stress tested they did fine. I cleaned everything and I have enough fans, even a button for extra fans to turn on.

The games you mentioned are CPU dependent and will cause more load on CPU. Make sure your CPU isn't overheating.
