My problems with BSOD started a while ago. Probably in first quarter of 2012. It lasted for at least half of year, and at the end of July they stopped. I can't remember what I did, I think I unninstalled nVidia drivers or sthg that was installed. Now, about a week ago, BSOD's came back. I attached all necessary files following [INFO] How to ask for help with a BSOD problem.
