Macbook screen goes blank

[ruane89]

Got it in feb and have had no problems, but when the cursor is moved to the top left hand corner off the screen and is beside the wee apple symbol. It goes blank for maybe a second and then thats it. Its really beginning to bug m now as its been doing it for over a week. Ive read similar problems but none that is the exact same as mine as mine only goes blank when ive placed cursor on top left were as others have to shut down and does it randomly please help

You likely have "Hot Corners" enabled, which activates the screen saver when you move the cursor to a corner.

System Preferences -> Desktop & Screen Saver -> Hot Corners button
