My pc has been locking up and when I shut it down and restart it I have been having problems. I have received the nvlddmkm.sys BSOD and the drivers will disappear. They will still be installed but my cards wont be anymore. They have also crashed and are no longer in the device manager when I enable SLI. I took the bottom card out and put it in someone elses pc and it seems to work fine. Using just the top card in my pc, everything seems to work fine. I have a legit copy of windows, I have been using the same key for a while now. I did install it from a burned disk though. Does anyone know why this would be happening?
