This sounds extremely bizarre to me, but maybe I don't know something that my PC manufacturer does, however either way I'm still encountering problems with my GTX690 SLI configuration and I'm pretty sure this is why. So after an hour or so this morning of wondering why my nvidia drivers are causing my computer to BSOD on a scheduled scan and why updating the drivers of the cards causes major non-functionality issues with my OS, I decided to just for the heck of it look at GPU-Z and see if there was anything wrong with the cards that are hooked up, and what I found is that Card 1 is an EVGA GTX690 and Card 2 is an ASUS GTX690. My first thought is that since they're both just reference GPUs there shouldn't be a real difference between them, but every time I reboot after updating the drivers I get a SLI connector error and then my computer sort of lags into a grinding halt where I have to do a system restore before the driver updates in order to get the PC to function again. I'm an amateur at best when it comes do all of this, so does anybody here have an idea what could be the issue?
