So.. I have 2 MSI 670 pe oc in SLI. I have had my computer for around 11 months. Everything has really been fine very little problems during this time period. Today, I go to turn on my computer and no signal is sent to the monitor. Switch the HDMI cord to other GPU and signal is good. However, SLI is no longer available/working. CHeck device manager and it says my card in my top PCI slot is no longer working/recognized "Standard VGA (code 10). The other card is working fine. Troubleshooting time... I first switch the cards slots to see if its a card problem or motherboard problem. When slots are switched, the same card is still not working. THis time I don't even get a code 10 problem just flat out no recognition (though fans are still spinning). So I am assuming it is a card problem. When I switched them back I get the same code 10 but the same card is still not working. I have not recently updated anything but I did try a clean install of the drivers but its still no go. I did install far cry 3 yesterday it played completely fine so I doubt that caused it. I plan on RMA but was wondering if anyone else had any idea. I know NVidia says CODE 10 is irq conflict but it doesn't follow that only one card has this regardless of position.

I had a problem like this as well but I was 2xRadeon 7850's. Very perplexing to me. Spent hours going wtf. You are gonna laugh when I tell you what the fix was for me. I felt like a noob. When I installed my second card I must have tugged a pcie power cable and the other end came loose but not fully disconnected from my power supply. It worked fine for awhile then must have vibrated loose over time. One day no second card recognized. I thought bad card to at first. Then switched card positions. Wait both card work mobo must be bad...lol. Anyway I figured it out when I realized I always kept my pcie aux power cables in same location. Switched it up and bam card worked in second slot. So I would recommend checking to see that the power being supplied to your pcie auxiliary cables is good.
 
This happened to me, a PCIE wire came loose, so in result the card wasn't getting power Even if the card is spinning and is getting power, loose cables can cause it to malfunction and not work correctly.
 


Unfortunately this isn't the case for me. When I switched the slots I also switched the power cords that were feedig the cards. Cards a no go in both slots It's seems like the card RMA HERE I COME
