Alright so A bit about this I talked to a guy on the phone about 2 weeks ago on the evga support hoping it would clear up the full system freeze. I have been monitoring the card typically after about 36 hours or so the system will start to drop fps where nothing displays for a few seconds but you can launch programs etc so not a system freeze tested it on time with just launching keyboard short cuts. The temps are the card are running fine I am running the newest beta drivers. System was running fine till put in the gtx 780. I sold the old card I had so now way to see if that helps.
 
Things I have done already
Upgraded to newest bios on the card only fixed full system freeze
Have tried every version of the driver that supports the card no luck with those
have tried maximum performance option in nvidia control panel no luck
have enabled kboost with evga precision no luck
Have enabled both performance and k-boost no change there
Redone all drivers removed evga precision and rivatuner 
Also have done vsync on and off trying to see if that would help in global settings and games
 
All in all i'm running out of ideas really don't want to rma because I don't have a backup card the x79 series does not have a built in gpu so id be without a computer till the turn around on rma
 
 
 
Now about the system
I am running a asus rampage 4 extreme mobo on the newest bios have even played with the older one
64gb of ram vengeance series 32gb kits two of them
Raided ocz vertex 4 128gb two of these
ZX series 1250 watt power supply
And 4 additional hard drives
Windows 7 Ultimate x64
System was built November 2nd 2012
 
Please help me i'm going crazy 

Welcome to my hell too. 36 hour driver crash....for the lose. It must be our weak power supplies  

Is you windows updated just like mine? Nothing left to get?

The only thing I have tried that isn't on your list and I haven't gotten to test out yet is disabling the GPU High Definition Audio in the Device manager which leaves on Realtek behind. 

Ok just wondering. Someone said they solved in the Nvidia boards by avoiding all this years win 7 updates. If I have to pull updates....which is ridiculous.....that nvidia doesn't test on an updated OS (hello real world calling.....perspective)...well then its back to AMD.

First remove -ALL- things to do with nVidia(Geforce experience, physx, drivers, precision, afterburner, etc.) Restart, run a driver removal program. Restart. Download latest driver. When installing select only Driver and PhysX leave others unchecked. Select the option for a clean install. See if that fixes your problem

Done that a few times no luck with it kinda annoyed with nvidia at this point and the restart really is the only way to fix it or a hard restart if you get full lock up

now I want to know about the snazzier program to see if i can find the issue in there 

I believe its the driver as I had the same symptoms with my GTX 480s SLI.  Used a program to erase all traces of the drivers and cleaned registry etc.  Used the recent released HQL driver and beta and both were the same outcome.  I rerolled back to 314.22 and have been ok browsing etc.  Haven't gamed yet.

I can confirm this has no effect. This problem persists across formats and I never install more than the pure driver and phsyx to begin with so there is nothing to remove.

Well new event just got a bsod out of no where locale id 1033 fun times
 
So at least i got my 36 hour reboot out of the way I guess humm wasn't playing a game wonder if it bsod's if your not in a game and if your in a game it locks up?

ya I've noticed event log really doesn't help worth a darn with this and I doubt half of us getting our Psu killed unless nvidia put out a really messed up gpu series

I agree with you there its not easy going onto the phone always and talking for like 2 hours to support just for them to say rma which whats the point is everyone has the same issue
