Motherboard causing GPU failures?

[Syephro]

System Specs
Windows 8.1
Intel i7 4770k
NEW EVGA 750w 80+ Gold (Original was 800w from Rosewill)
Corsair 8GB RAM
Gigabyte Z87 HD3
In this order: GTX 770, GTX 750, GTX 980

So, I've had this system built for approx 2 years now from Cyberpower. But just in the passed month or so, I've tested 3... THREE gpus and I've got the same problem on all 3.

To start off, the GTX 770 began to screen tear, artifact, black screen, crash the computer when I'm playing games, text blurring was usually the tell-tell sign it was about to shut the computer down, and buzz... The works. The GTX 770 was what came with the system, so it's lasted a good while. The temps never got above 65C, though, which was odd.

I had planned to order a new 980 to replace it and was borrowing my friend's GTX 750 until it arrived. I noticed the same thing start happening with his card (which had ran flawless in his system). Black screens during gameplay, crashes the computer, (no screen tearing or artifacts yet). Same with this one, the temps never got above normal when under load... Strange.

My 980 arrived Monday and I've been using it non-stop since... Well, the same thing has started to happen again. Black screens during gameplay, games crashing to the desktop, computer crashing without warning during a game... It's just really odd.

Motherboard temps are around 25C, which isn't anything to throw flags at.

I don't want to order another Motherboard and that not be the problem. At that point, I'd have basically rebuilt my whole computer aside from the ram and the processor.


Any ideas before I order a new MSI motherboard?

I don't think it is the motherboard, but to be safe you can contact Gigabyte to ask. I have used Gigabyte for YEARS (since 2007) and swear by them.

Have you tried the on-board graphics to see what happens with that instead of always testing with a PCI-e card?

Do you have the correct power cord configuration(s) connected? I know that sounds silly be you'd be surprised how many of those I have seen on here.

Have you tried to flash the BIOS to see if something in there was miss-configured?

Have you run a benchmark/stresstest program and review the detailed results? (3DMark, PassMark, etc)

Don't forget a general Memtest x86. Bad system memory can cause inexplicable behavior.

Power supply would have been my first guess, not likely to have two bad ones.

Not ruling out the motherboard, bad slots do occasionally happen.

Here is a fun trick that fixes a surprising number of problems. Visually examine how close to 90 degrees your video card is to the motherboard. If you see that it is off a little bit, loosen the motherboard screws, re-align, and screw it back down. Thermal expansion over time can cause a motherboard to creep and slowly fall down (when mounted in a standard tower) This can result in intermittent contact between the GPU and slot. Usually causes artifacting and texture load errors.

Here's some pictures of what the graphics cards do from time to time. And the 770 is much more frequent. Almost unusable. But, it never gets above temps or anything and still works flawless on games before it explodes lol.
