Is one of my GPU (GTX 760) dead?

[DapDingo]

Greetings,

It seems that after updating my drivers to the latest (350.05), I cannot play games (Skyrim, D3, SCII, Furmark) in fullscreen with SLi anymore. The video card drivers crashes and freezes my computer. I thought this was just a driver issue, so I returned to my previous driver (347.88). The issue still remained. Running games in windowed mode and single GPU works fine. I tried switching out my video cards to the second one, but I get no video from it. After uninstalling the drivers, I did get the basic video (low resolution). After reinstalling nVidia drivers (347.88), I no longer get video. When I switched back to my first card I get video. Does this mean my second gtx 760 is no longer working?

Was it just a coincident that after installing the drivers my second card died? Fans and gpu detection works perfectly. Temperatures do not rise past 70. Thanks for taking the time to read, and thanks for any responses.

My specs:
i5 2500
AsRock P67 Extreme 3 Gen4
16gb GSKILL RAM
MSI twin frozr GTX 760 Sli
PcPowerandCooling 750w Silencer mk ii
Samsung 840 128gb
Windows 7 Home Premium 64 bit

Edit: I completely cleaned my computer between driver installs/uninstall. Used drivesweeper in safe mode after regular install.

Try power and unplug PC for 30 seconds. Also try "clean" install option? Yeah seems like some problem reports with 350.05

Yep, everytime I installed drivers I use that option. And everytime I uninstall I make sure to go to safe mode and use drivesweeper. I've also completely powered down my computer for several tens of minutes. No luck.

So you are completely removing one card and getting no video?

That what I would suggest

Try one single card, in one PCIe slot then the other. Stress the card(s) to the max.

If you have already tried that, are you using the same power connectors from the PsU?

It might be crazy but you could try using the good cards pcie power connectors.

It is sounding like a bad card though. I would stick to one card at a time to troubleshoot this. Hopefully you have a warranty

I have a friend who had that happen. Put it in single 1x card in your mnaching,, perhaps.

My first video card alone gets video. My second video alone doesn't get video with drivers, but it gets videos without drivers. I have an 8 and a 6 pin power for each card and I've swapped them around to see if its the power. Doesn't seem to be.

thanks for the tips

 

[tweakboy]

try both 1 by 1 .... and you will know whats up more!

You still have a warranty?

I've also completely powered down my computer for several tens of minutes. No luck.

Even unplug? nVidia cards have had several reported instances where power needed to be totally removed to remove "sticky corrupted state" that survived reboot and even power-button cycle.

Well, you took the card out so I'd say power was fully removed from the card ... :whiste: :awe:

 

[DapDingo]

Thanks for the responses. I think I'll have to send it in. The only thing I haven't tried yet was completely removing both video cards and do a power cycle and then reinstalling them. I'll do that tomorrow.

^This....try one card in the PCIe slots to make sure that was/is not the issue.
