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.
