PC freezes with every game, but only at the first launch.

[Shontodin]

Hi there, I really hope to find an answer here at least.

I recently assembled my new pc, specs are lower in the post, and since the first time whatever game I play the pc freezes after like 5-10 mins, but only the first time I launch it. I mean: I power on the pc, start playing something, it freezes, I have to reboot manually because the whole pc freezes, and after that if i run that or another game it works. I can't get why and I'm on this since last month.

I 'm pretty sure it's not a driver or OS issue because I did a clean WIn10 Pro installation, I also formatted it 3 times, always everything totally updated. I even tried to install Win 8.1 Pro but nothing changed; disabled quick/fast reboot (don't know how it's called in english OS). Games tried are: The Witcher 3, Batman Arkaham Knight, Hearthstone, Wildstar.... but if i don't run any game but i.e. I stay on web or listen to music there's no problem at all. Btw, no overhating problems, and already tried also to flash bios. 

PC specs:

- CPU: Intel i7-6700k Skylake

- Motherboard: Asus Maximus VIII Hero
- Watercooling Cooler Master Nepton 240M
- Ram: 4x4Gb Corsair Vengeance LPX DDR4 2666MHz
- Grafics: 2 x Asus GTX980ti sli mode
- Audio: Soundblaster Recon 3D
- Audio speakers: Logitech Z906
- Monitor: Acer Predator x34

- PSU: Monolith x LC1200

 

Sorry for bad english and thanks to whoever will stop by and give his 2 cents.

Are you overclocking anything? What are the games installed on? SSD, HDD?

Did you try any process of elimination stuff? Like use 1 video card or the onboard soundcard?

 

also what bp is asking^

Try with one card only first and see if that remedies the problem.
