My driver was updating, when it finished and was suppose to be restarting. It stated that the computer would experience a black screen and possibly light flashes. It did have the black screen and then about every minute it was flashing to a screen that had the AMD processor info. This has been going on now for about 4 hours with no sigh of quitting. I can't get my pc to do anything else. It never finished restarting just keeps with the black screen and flashing
