In short, like everyone else, the new driver packages are completely unusable for the GTX 860m. Took me a while to narrow it to the driver, and I also determined that uninstalling the GeForce Experience suite did not help fix the issue. The freezing / crashing starts occurring as soon as Windows 10 starts up. 57 hotfix, my Lenovo y50-70 laptop becomes completely unusable. My screen always stuck with few seconds on booting and BSoD of VIDEO_SCHEDULE_INTERNAL_ERROR and CLOCK_WATCHDOG_TIMEOUT also appeared randomly even without any operating like drag and drop or opening my outlook. Today my gaming laptop with GTX 860M crashes after the driver version 378.49 updated, the environment is Windows 10 Version 1607 64-bit on Lenovo Y50-70.
