Random black screen crash after adding second card?

[FluffyNuggets]

I just added a second 670 FTW + and now my computer will crash while gaming. The screen goes black and I have to hard power it off by holding the power button down.

No idea what the issue is since I never get an error, just crashes.

Here's my specs:

ASrock Extreme7 Gen3 Z68

I7-2600k @4.5Ghz

Corsair Vengence 1600 8GB

2x EVGA GTX 670 FTW+ 4GB

120GB Intel 320 Series SATA 3 SSD

120GB Kington HyperX SATA 3 SSD (RAID0)

WD Caviar Green 1TB SATA 3 HDD

WD Caviar Blue 1TB SATA 3 HDD

Corsair AX850 Gold

YAMAKASI Catleap Q270 2560x1440 @120hz

The CPU and GPU's are both water cooled so the temps aren't causing it.

Thoughts?

maybe you should test the second card, cause if you havent tested this card, this card might just be causing the problem.

 

i discussed this with a friend of mine, and we talked about the PSU, however we decided that cause its an AX series and 850 it should be OK. but just check the TDP for all the components and see if it surpasses the number on your PSU

The PSU is fine since I can play BF3 forever without it crashing. However, whenever I play just about any other game it crashes like that. I've had games freeze before with a single card but I could always just quit the game and it would be fine. 

 

I'll go ahead and disable the old card and try the new one and see if it crashes. What happens if the game runs fine with that card but wont when running SLI? I have the cards in the specified slots ASrock wants. You think it could be a driver issue?

yeah it could be just driver issues. so you'd wanna just delete all the drivers for them and then obviously download and reinstall. (have them ready on a memory stick for ease)

 

another point that you should consider is, are the cards identical. same company, same version, same specs etc etc

Yes the cards are the exact same including memory. Not sure about the version since I'd assume that would be the same.

I'll try reinstalling the drivers first and see if that fixes it before I do anything else. Should I have downloaded the drivers again after I installed the second card? I assumed it would work after the card was installed.
