Windows 8 Windows 8 laptop flashes black from time to time

[JesusGonzalez2]

My computer is a Dell Inspiron 14, 5000 series that runs Windows 8. It has an Intel Core i7 and it uses Intel HD Graphics 4400.


Every few hours, the screen sometimes flashes black; but the computer runs just fine. Using event log, found that a process called "UserModePowerService" happens each time the screen flashes.


This is the full log:
