I currently have this issue as well but it's more severe (TDR's and random reboots, etc). Trying rolling back to a previous driver, check your event viewer for a more in depth explanation (what is it?). Trying using a tool called DDU to reinstall your driver (do a CLEAN Install). This issue along with others does annoy me like crazy but im not playing it now and I'm waiting a couple of months, then I'll buy myself a new gaming laptop (currently have a desktop with a year old GTX 970). I use FSX for the time being.
Try running memtest to check your RAM, since it could be a memory issue.
