Computer Hard Freezes When Gaming

[kil0watt]

When I first built my computer, I had a Gigabyte 560 Ti and my computer would freeze up randomly while I was in the middle of a game. I dealt with it because it wouldn't happen too often. It got to a point where it would happen VERY often so I thought it was a faulty card and just took it out of my computer and didn't use it. Fast forward 2 and a half years later and I just got an Asus Strix GeForce 950 OC. Just booted up The Culling and not even 10 minutes of runtime and my computer freezes in the exact same way it did with the old card. My computer never freezes when I'm playing something on integrated graphics at all. I've checked my temperatures and they're all fine. I've tested both PCIE slots on my motherboard and it does the same thing. Does anyone have any idea of what this problem could be because it's driving me crazy? 

Specs:

• i5-3450 @ 3.1 GHz 
• 8GB of RAM
• 850w PSU
• Gigabyte Technology Co. Ltd. B75M-D3H
• ASUS Strix GTX 950
• Windows 10

Do you have a spare motherboard or know someone that does that would work with your build?
