GTX 295 -- Only seeing 1 GPU?

I just picked up a GTX 295 off of eBay (mainly to use for CUDA -- should be a good card for that.)

I installed the card and booted up, it immediately recognized all 3 of my displays and had two GPUs listed. I spent some time configuring everything, installed some new software and then rebooted.

On reboot -- my HDMI display didn't come on. I went into the driver and there was only 1 GPU listed. Before this, it listed 2 GPUs.

Device manager doesn't show anything else. The NVIDIA software doesn't show anything else. It's just like one of the GPUs doesn't exist!!

I pulled the card and reseated it. I completely removed power for 20 minutes. Nothing has helped.

Did I get someone elses bad eBay card? If so.... why did it work the first time?

Did I just have bad luck and it fried on the second boot?

Is there anything I can do to revive it?

So if you connect only one monitor what happens? can you use a dvi cable this time?

The card has 2 DVI connections and an HDMI connection.

When it was "functioning" it showed the 2 DVI connections on 1 GPU and the HDMI connection on another GPU. I was able to utilize all 3 of those.

Now, I can only see the DVI connections. Both of those function correctly.
 
So if you connect a single monitor via a dvi cable you can see 2 gpus in nvidia control panel?

GPU-Z only shows 1 gpu (lower left corner.)
 
What is your PSU, make sure the power plugs are snug as a bug in a rug, uninstall drivers and reboot. Report results.

It's a cooler master 750. Power cables are all snug and the GFX card is showing green LED on PCB1 and blue LED on PCB2. I've read that a red LED indicates a power problem.

Uninstalled drivers, ran driver sweeper in safe mode and tried both WHQL and BETA drivers.

Even without drivers loaded, GPU-Z reported a single GPU. When this card was functioning -- it showed 2 GPUs.
 
I took the card apart today to verify that he internal SLI bridge was connected. It's a tricky ah heck but I did remove and re-seat both cables. Still the same. 🙁

Anyone else have any ideas?
 
Looks like this is a common problem for the 295's...


Many would post that by unplugging the PSU, waiting a few minutes, then re-plugging/starting the machine that it would show up again but re-starting / re-booting normally afterwards will show it as gone once again. I had yet to see anyone find a 'fix'. Could be the seller knew this, knew it would show up upon initial install...
