Hi

I have just installed 2 780s and I think they are causing the computer to crash non-stop. The PC started to crash when I started a game, but a few minutes later it is now crashing when surfing the web loking for answers to this issue!

The error report is as follows

Log Name: System
Source: Microsoft-Windows-Kernel-Power
Date: 13/08/2013 16:56:39
Event ID: 41
Task Category: (63)
Level: Critical
Keywords: (2)
User: SYSTEM
Computer: Matt-PC
Description:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
Event Xml:

41
2
1
63
0
0x8000000000000002

127697

System
Matt-PC

278
0xfffffa800d2a4010
0xfffff8800911f700
0xffffffffc000009a
0x4
false
0

To be honest I don't understand any of this, apart from the fact that an Event 41 means something has caused windows to shut down due to an unforeseen event. Whatever that means. I have read that people who get this issue usually resolve it by uninstalling drivers for the cards and doing another install, which I've done. Nothing has changed. I thought it might be an issue with the new monitor I have, but it crashes on an old monitor as well - must be the cards. NVidia panel recognizes the two cards, as does windows. Literally every game I open - Crysis, metro, guild wars, doesn't matter - it WILL crash.

Can anyone make anything of the above error?

PSU is OCZ 1250 w
Changed from x2 570s

Would shifting them from x2 pcie 16 lanes to x2 pcie 8 lanes make a difference?

You need to do a clean boot and Driver Fusion / CCcleaner wipe of the previous GPU drivers.
This is a fairly common occurrence.

The 780 can't use older drivers at all.

Steps.
type "msconfig" and setup clean boot state. http://support.microsoft.com/kb/929135
Uninstall drivers through control panel.
Reboot into Safe mode.
Run Driver Fusion - remove all Nvidia files. - you can keep C:\Nvidia folder though as it just has the extracted drivers.
Boot back into windows normally. You should still be in clean boot state at this time.
Optional - run CCcleaner
Check that any Anti Virus program is not currently running, or pause, or shutdown for now.
You should still be in clean boot state.
Now Install latest Nvidia Drivers.
reboot.
msconfig - to go back to normal startup if you want.

Happened to me too when first installed my 780 from my GTX470 - even after uninstalling previous drivers through NV tool.

If they don't get the thermal pads on the memory or mofets just right that could possibly cause it too.
I second trying each card individually as well.

Also, as is mentioned by a disclaimer sheet that comes with each GTX 780, do you have the latest BIOS revision installed?

Ahhh, not this. Didn't read this. Didn't see this anywhere.

Just read it. To be fair it says may conflict. I've always worked on the principle that I never update bios until I start to get issues. Maybe this is one of the issues. Trying to uninstall as per previous advice atm.

Done all of this but exactly same issue. Cannot process three frames of a game before a crash.

Thanks though. Will try cards individually and then update bios.

I have read that Asus boards in particular are susceptible to older BIOS software being incompatible with the GTX 700 series. Really, this is the first that I have openly seen even GPU manufacturers having such specific warnings packaged with their cards, but I suppose it does make sense considering that such issues have occurred in the past, starting with the 400 series.

Yeah OC is fine. And I put it on stock as well just to check. Updating bios now. It was a while ago that I did it.
