Card going bad? Bad Drivers? Faulty motherboard? I need help.

I'm running two Nvidia GTX 580s in windows7. I use them mostly for multi-display (3 screens) but occasionally in 3d performance for gaming.

This afternoon when my PC awoke from its sleep I had two cloned monitors instead of the usual 3 with extended desktop. I tried changing my DVI port and my PC immediately detected the third monitor and after some brief config all was back to normal. The next time my PC awoke from sleep mode it was back to two cloned screens.

Both cards are detected in device manager and appear to be working properly. Both look to be in good working condition, are cool to the touch and have unobstructed fans and minimal dust. Both cards are detected by Nvidia settings. The extra card shows up with no attached displays but will allow me to use it for physX or SLI 3d performance. I have tested my monitor/wires by plugging it into my onboard video as well as the primary GPU. It just seems like the DVI ports are not responding on the second GPU.

I've tried updating drivers and removing the cards via device manager and allowing them to be re-detected. Nothing seems to be working. I think the second card is still under manufacturers warranty however I need to know if this is just a weird issue. The fact that it lost a monitor after sleeping both times leads me to believe its a quirk and not a faulty card. Sleep mode has done stranger things to my PC.

What are some next best steps? is there anything else you would try?

UPDATE:
When my PC woke up this morning everything was back to normal. I'm not sure what is causing this.

If it happens again try reseating the the graphics card, if it continues i would contact EVGA and check to see if an RMA is in order. One thing you did not mention is the make and model of power supply.

Thanks for the thoughts. I'll try reseating the card now. It just did it again. It seems to happen after I let the PC Sleep. I'm not sure why it started working this morning.

Do you think it could be the PCIe slot? Maybe I should swap them on the board and see if it makes a difference? I have a lifetime warranty on them but I imagine EVGA will want to know its the card and not the slot?

Sorry I must have overlooked the power supply. I edited my OP to include it. here is a link for you though: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139014

Power supply is more than enough, very good quality! Go ahead and switch cards around to see if their is any difference.
