Another unknown: If the driver worked and suddenly stopped, is it the driver?
Seen a lot of this: Usually right after an update of the net driver or installation of net-affecting software (connectify, utorrent, various virtual software (VMs) etc.). Mostly updates.
Maybe rolling the driver back is an option...? lol
Just last night I was messing round with VBox and all of my net drivers became kaput. Tried uninstalling/reinstalling the drivers and VBox to no avail. Wasn't the drivers at all: It was some unknown compatibility issue created that was only resolved from a backup (image).
As stated: If this all the dmp found; it only covers hours. Something caused it. OP states it is uTorrent, perhaps. My be would be that this is not the first time uTorrent was run on target machine. All of a sudden?
