Followed this guide to the letter, even unplugged my computer from the net but I encounter one single problem. Every time I restart my computer (into safe-mode or normal) it decides to automatically install drivers for both of my GTX 285's. I've already gone to Computer > Properties > Advanced > Driver Installation and turned off auto-installing so not sure how it keeps happening. The drivers it keeps giving me are called (Microsoft Corporation WDDM 1.1) Eventually I got tired of uninstalling and restarting and just installed the 286.96 drivers over them.
Also on that note, should I go back to the 197.xx drivers? These 286.xx are causing me to run a bit hotter than before. I now idle at about 47-53c and on load I get between 64-73c when before I idled at 42-46c and on load I was 54-65c. The temperature spike isn't life threatening but the cooler the better, right?
