Computer restarting upon stressing new GPU

Hello,

I recently bought a new EVGA NVidia GTX 970 SC from newegg and popped it into my computer, it appeared to be working all nice and dandy but whenever the card gets too much load on it the computer restarts.

I have a 3 monitor, 5760x1080 surround setup that pretty much ensures a restart anytime I start a high graphics game. I found I am able to play games fine on one monitor so at first I thought it was a bad driver that just didn't have good support for surround yet (even though I'm using the newest driver released today), but upon trying minecraft (which I would image has little to no usage of the GPU) the surround feature worked just fine.

I also considered the possibility of it being my PSU not supplying enough power, which considering I got a larger PSU at the same time as this card is very possible. But I upgraded from a 650W to a corsair HX850 which not only is far more than enough power for a single 970 but it also proved itself already as I ran my old gtx770 AND a friends gtx670 together, the 770 running games fine on surround and the 670 running an additional 3 monitors aside from the game.

After that I thought it may be a problem with steam and surround gaming, since all the games I was trying were off steam, so I tried FarCry4 on all maxed out settings (running from Uplay, not steam) and it actually ran fine for about 15 min. but eventually it caused a restart too... I also ran Unigine Heaven Benchmark which ran for a couple minutes, but that crashed it too... the only thing I can thing of is that when the graphics card reaches a high enough load it caused the computer to restart, it's not temperature because it would crash right away running 40C on Portal 2 and keep running for a couple minutes running 70C on the benchmark, so I honestly have no other clue what could be happening.

Do you think my card is faulty somehow? Is there some other test I can do?

Thanks!
 
Solution
try underclock the graphics card gpu and ram to nvidias reference specs and see what happens. Wouldnt be the first time a factory OC card is unstable in certain scenarios.

iam2thecrowe's solution seems to be it, I downloaded evga's precision x16 software and used it to reset the card to it's original 1050mhz of the non superclocked edition and so far games are running fine. I'm going to keep testing on games for a few days, but if all seems to work fine I'll probably go figure out how to increase voltage a little and keep it running at the Superclocked speed (or more :D).

Thanks for your help!

okay, I have been testing some more and it looks like it only works on some games and even then it's not consistant. It appears to be better but now, for example, as soon as borderlands 2 starts loading the dlc's (even before main menu) the computer restarts. I'll keep you posted but as of now I'm considering just doing an RMA on the darn thing.

another update, interestingly enough it now looks like it is NOT the gpu (somehow, i have no clue at this point). I brought my old GPU (gtx 770) out of the box and swapped it with the new 970, half ready to file for an RMA on the 970, but then the 770 caused the exact same problem! A friend of mine tells me he has been having a similar problem with his 970 and so we were sure that it was the gpu (even though the likely hood of both our gpu's being messed up is extremely low) but now he tells me he has been looking around and thinks it's a windows driver problem. I have updated to the latest driver from GeForce experience and doubled checked that I have the latest driver for the card under device manager. I have not done any major software changes lately so I don't think I could have messed up any system files, is there some other drivers I should check?

For now I'm going to try downgrading my driver to one that worked for sure on the 770 and see if that does anything...
