My SSD threw me a curve, I rarely let my machine sleep it is either off or on. Last night I ran down to supper and just left it on, it was set to sleep after 30 min. I came up after dinner wiggled the mouse and blue screened it. I searched the net and found out some SSD's have an issue with sleep, in thinking about it is no need for the drives to sleep NO moving parts. So if you have yours set to sleep you may get a blue screen along the way, my SSD is a little over a year old Intel 120 SC2CT120A3 I believe new ones may not have the issue.
