It sounds to me like your PSU isn't sufficient. Try it with a more powerful PSU, if you don't have on you can pick up an 800+ watt PSU for less than $100
If this turns out to be the only thing that may be the problem I may have to do just that, if I did I may just say the hell with it and overkill the psu and get like 1000watt+ just so I wont have to buy another for a very long time.

That psu is perfectly fine for one 7970.

Go back to stock clocks on everything, reset your bios (clear cmos). Run stability tests on the cpu first and then the gpu. If it crashes with either then it narrows down the problem. If both pass, then it could be a bad oc on either. Progressively bump up the clocks on your cpu first. Make sure you run a cpu test after each bump in speed.

Edit: total system power draw at the outlet (factor in the conversion -100w):

I thought 650 watts would be enough. By no means plenty but enough. and I will go back and do what you said hopefully all works out....

I have two 7970's overclocked and they have to be pulling more than 400 watts each when they are being stressed mining because they shut the computer off. I have done some testing on my own and that's what I have concluded. I'm currently using an 850 watt PSU but when I put my system in my case, I'll be using a 950 watt PSU.

I'd wager it being the PSU. 7970's can pull a LOT of power.

I think its the PSU. Im folding on two at the moment and a 3770 and pulling 680 watts at the wall.

Pull the power cable from one card and run with only one card and see if the rig still shuts down.

There is obviously no leaks and my temps are normal so nothing is over heating I really dont even know what to say except for please someone try to help me figure this out.....

Updated with more info:
System Spec:
CPU i7 3770k OC'd to 4.5ghz
GPU: 7970 OC'd to 1200MHz and memory at 4650MHz but I dont think the GPU OC is affecting anything because it has crashed at stock speeds also
MOBO: Asrock Z77 Extreme4
RAM: 32gb at 1600MHz
SSD: ADATA 120gb
HDD: 2TB western dig. caviar gree
PSU: Seasonic 650watt gold plus rated
OS: Windows 7 Ultimate 64bit

WC setup:
EK waterblocks on the 7970 and 3770k
dual swiftech mcp655 pump with bitspower modkit and pump top
danger den radiator reservoir
alphacool monsta 240
and bitspower compression fittings (1/2 3/4) across the board except for a set of koolance QDC

As far as when it crashes. It does crash a little more often in games or heavy tasks but it also crashed on simple things like browsing the inter webs or opening and inter webs page. Also ocassionaly when it turns and it goes to automatically turn itself back on it will sometims immediately shut off again....

I will post a video build log hopefully in the next few days and if its not figured out by then maybe a build log will help out.


Not sure where ppl are getting op has two 7970s, ???

I only have a single 7970 your right

Just double-checking, you have automatic restart after crash turned off I assume? It's on by default when you install Win7. Control Panel > Advanced system settings (system properties) > advanced tab > startup and recovery "settings" button > in the system failure section clear the checkbox labeled "automatically restart".

You can also check the event logs for crashes or other critical events. One of my favorite ways to do this is with the reliability monitor since it has a nice timeline display. Open up the Run dialog and enter "perfmon /rel" and look for red x events.

Agreed on both counts, especially that the first step should be go back to default speeds and voltages on everything. IMO by the symptomology it sounds power- or heat-related so that's where I'd focus my investigation.

FWIW, I think I have the same PSU (x-series?) and it's a solid unit. Seasonics have a little overhead above their rating, but if you are overclocking the card AND your CPU then it's possible that pushes it close to the max.

If going back to stock speeds doesn't change anything then check your board for blown caps. After that the fruit isn't quite so low-hanging so I'd do a tear-down and rebuild it piece by piece, swapping in other parts if you have them available.

One more question though... you were using the exact same hardware with the exact same overclock on air, and everything was fine?

Im gonna run stock gpu speeds for awhile and if it still crashes I will run stock speeds on the CPU too. If it ends up being that my OC's were drawing too much power will getting a more powerful psu allow me to run my OC's and fix my problem? And to answer your question yes literally the only thing that got chaged was the added WC setup and I doubt this means anything but I changed the were my capture card and video card were located (changed PCI ports). Oh one more thing that I changed to be able to put in my WC setup I had to take out my drive cages and 5.25" bays so I had to use velcro to put my SSD and HDD on the back panel. Its very sturdy and the only problem that there might be with that is vibrations from other components.

It crashed like 5 min. after I put it back on stock speeds on the 7970 and now I am running UEFI defaults. But its really weird it seems like it crashes when I am opening and Internet page whether it be chrome or IE.
