It could be a bunch of things:
1) Overheating. The temps you posted are pretty high. Especially the cpu's. What are the idles?
2)Power consumption. Heavy duty, high end gpus have higher demands. There's a chance your power supply can't provide.
3)Drivers. I've had my share of gpu related crashes/restarts throughout the years.

Back to the overheating assumption: During summer I generally avoid playing high end video games, since I have no air conditioner in my room.

- The temp while gaming is 68C at max (sorry i read it wrong), the idle is 40~47C
- Yea, i was thinking it because the PSU, but most of people said it wasnt, i will try to change to another PSU when i have money
- I tried 2 different GPU (Gigabyte 1080 Gaming G1 & Asus Strix 1070), so i dont think it was the GPU problem.
