Hello everyone!

First of all, my spec, speccy, and dxdiag:

Mobo: Asus Sabertooth 990fx R2.0
CPU: AMD FX 8320 Black Edition
RAM: Corsair Vengeance Pro Series 2x8GB
PSU: Corsair CX750M
SSD: Samsung 840 Series 120Gb
HDD: Western Digital 1TB WD1003FZEX
GPU: Palit GTX1070 Super JetStream (Radeon R9 270 OC is what i changed.)

Speccy:http://speccy.piriform.com/results/Xw52O2Tq437p3zxDiCIJTm5
DxDiag:http://data.hu/get/10135478/DxDiag.txt

A few thing in the DXDiag is in hungarian, but i hope its not a problem if u know what u are searching in it.

So my problem is, a few weeks ago i buy a Palit GTX1070 Super Jet Stream. When i installed it i reinstall the whole windows too. Every time i start up a game i will get random pc restarts. I belive it is more frequent if the graphich setting is ultra or high.I can play world of warcraft for hours without restart, but i cant play Overwatch for like 10 minute even in medium settings. I already checked the temperatures twice, and they are all good. I try older gpu drivers, i try to disable and uninstall Nvidia HD audio( i read somewhere it fixed someones issue). I updated my bios, and all my drivers. I run benchmarks for a good 20 minutes without problem (Furmark, 3DMark, IntelBurnTest or what) i read countless forums and tryed everything they wrote there but nothing help. One thing i still not try is to change the psu or RMA the videocard. But i guess if i can run the benchmarks without a problem, none of those should be the problem.

Come back with the news, for future researchers. It turns out to be my PSU cant handle the heavy load, so i ordered a new one.[EVGA SuperNova G2 850W] After numerious forum reading i find a thread with my PSU test and it says under heavy load it is very unstable.

Ps: Sorry for my english. I will update when i got my new PSU.
