I've had this Blue screen of death on Windows 7 for a couple of months, with crashing about 10 times a day. I've read and tried LOTS of things, but no good. THEN, I read somewhere that a windows update KB2670838 could be the trouble. I found it and deleted it, and [so far] lap top hasn't crashed! In fact, I've even got the Norton 'Safe' icons back for each web site. I hope this works for you!!!! ♥♥♥
