Hi guys.

As the title says, my second GPU is no longer recognised in bios of my Asus Rampage IV extreme mobo. I have x2 evga 570s in sli. Everything has been fine until yesterday, when I went to change something in nvidia control panel and saw there was no longer any option to enable/disable sli.

I went into control panel and saw that only one of the 570s was recognised. I then went into rampage IV bios and saw that even here only one card was recognised. I can't think what has happened. I checked all connections to and from the 2nd gpu and everything seems fine. I can't pull the cards out and test for the pcie lanes because I am watercooling the cards and this would be a mammoth task for me at the moment - of course I will eventually if i can't resolve the issue with less dramatic action. I did however unplug the lead from the monitor to the first gpu and plugged it directly into the second gpu. I didn't get a
signal.

I recently updated the bios for the first time, due to increasingly random crashes, BSODs and long loading and POST times. I updated to 2105 version. I also updated the chipset from the Asus website. I don't think updating both has anything to do with the issue though, since I did this a week ago and could use SLI up until yesterday. I am really stumped.

I am not very techno savy when it comes to finding my way around bios or troubleshooting hardware problems, so I thought I'd post here and see if any kind soul could help me out. And yes, I have the latest nvidia drivers installed for the cards.

Many thanks

PS - wasn't sure if this belongs to motherboard forum or GPU forum. Sorry.
