Various BSODs about ntoskrnl.exe

[peoplecanfly]

Hello

Got a new Win8.1 64x PC with specs:
CPU: Intel Core i5-4440
Motherboard: Gigabyte GA-P85-D3 P85
VGA: Gigabyte 2048Mb GF GTX 760 OC GV-N760OC-2GD
RAM: Corsair DDR3 (CMX4GX3M1A1600C9) 4Gb x2
SSD: Crucial M500 CT120M500SSD1

Every 1-2 hour when i play any game i got BSOD (attached minidumps)

What i tried:
Upgrade every driver i can (even upgraded SSD firmware today)
Full chkdsk for both SSD and my old HDD (it take about 6 hours)
Memory test for RAM (some tool like memtest.org, really forget the name)
Adjusted RAM voltage to 1.65V like it says in specs from standart 1.5V

And it keeps happening

What else can i do to find a reason?
Thanks
