hi, whenever i use both my gtx 660 ti's in sli and alt tab, sometimes, it causes my screen to go black a few seconds, and say a driver has stopped working and has been successfully recovered. After searching for a while, it seems its something to do with timeout recovery or something like that, I went to an official microsoft page and used the microsoft fixit to extend the timeout recovery so this doesnt happen. Will there be any adverse effects on this? why does it only happen when I use sli?
