Hi, Please let us know whether did this issue occurred before? What you have done before this issue happened, whether you have installed updates, drivers or software? Please try to use Last Known Good Configuration to test the issue. If the issue persists, I suggest you can go to Safe Mode and Clean Boot. If there is no problem in Safe Mode, this issue should be related to the drivers, please updates all the drivers. If you can go to Clean Boot mode with normal screen, it issue can be caused by the third party tools. Hope it helps.Vincent Wang TechNet Community Support
