Possible Hardware fault?

[wsarahan]

Hi guys how are you?

I`m with a strange issue here

Even with my CPU at stock clocks when i run IBT or LinX after a couple of seconds or minutes my screen goes black and comes back with the message that the video driver was crash and recovered....

I have here 2 GTX 780 SLi, my PSU is a CoolerMaster SilentProGold 1200w

With softwares i can the that the 12v line is ok about 12.168

I tried turning off SLI and test some bencks but with both cards attached and i had no errors, the issue here is that i can`t test a stable OC because i always receive this black screens and have to stop the tests, but today i realized that happens with stock clock too?

What i supossed to do? My PSU could be the problem? It`s almost new one?

Thanks

Edit:

Well guys i removed both cards and tested then one at a time

The same thing happened with only one card at the rig, so i think that could not be the cards, what sould we try now?

Thanks

When you say it only happened with 1 card, when testing on their own did each card cause the same crash or only 1 of the cards cause the crash?

What is the rest of your spec? I know some motherboards can cause issues like this if the CPU is overclocked as well as the GPU's as they cannot handle both.

To eliminate the PSU, do you have a multi meter to test it with?

I have had this happen a few times, no idea why it does it. The last time it happened was a couple of weeks ago, just happened the one time and has`nt happened since. Usually just happens when I`m on the internet, You tube, forums, but it`s only for a split second.
I don`t think it is a hardware problem, more Windows and your Nvidia driver.
Are you using the latest Nvidia driver, if so, try rolling back to the previous one and see if it still happens.
