Graphic Card dead?

[Pumaxcs]

This one happened awhile ago and today I got around to test a few things out and I've run out of idea's and fear the worst.

First flag that I should have noticed was when cleaning my PC case of dust maybe two or three months ago I noticed the cards had different temps, one I had plugged my DVI into was warm and the other was much colder. Told myself under load I'm sure they would even out and moved on with my day. Recently I bought a new screen, gave my old one to my brother with his PC I built and got me a ACER 23-inch, and while going through my nVidia control panel double checking the screen resolution I noticed that my SLI wasn't enabled and it only recognized the one card. This was the last red flag that I decided I should look into it. I've tried reseating it, making it the primary in the SLI, running just that card but, the only thing I haven't tried is switch the ports to see if its the motherboard that is bad and not the card because the fan s still spin but nothing on the card is recognized. I'm posting this so while I'm switching that around maybe someone else has an idea of anything else I could try. I'm planning on doing some upgrades around Christmas so its not a crippling thing and its about two years old so I know warranty is gone. Anyone with idea's though I'd listen.

So it didn't work when you made it the primary in sli? Did you just use that one card and take the other out? I know I've randomly had my sli reset to disabled before in the Nvidia CP.

I'm back and its all good. Took the card out and put it in the slot that was working with the PCI power cable from the other card and it worked. Tried it with other PCI cables it had been using and it didn't. Tried the same with the other card and same results. Reseated the PCI cables form the PSU (modular) and everything clicked back on and everything is enabled. I almost broke Windows by the amount of times I restarted though.

So was just a lose connection from the modular cable in the PSU? That's always the best kind of fix .
