My laptop began to crash this last week, no new software nor hardware has been installed after this week. It crashes a while after utorrent starts, and seems to be ndis.sys related. I've seen a lot of threads on this subject, and tried some solutions with no results. Also, as the attached files may show, I have non matching ram dimms, but I don't think this is the issue because the 2nd dimm was added a month ago. I've attached a .rar file as the rules require. Hope to hear some feedback.
