Suddenly my laptop has flashing black dots every couple seconds or sometimes a bit longer. It was fine before, the only thing I did was play M&B WFAS.

Ideas?

edit: I didn't hit it or anything.

Playing a video game may cause you screen resolution settings to be changed to the resolution selected in the options menu of the Video game in question. Try changing your screen resolution and see if it improves.

That may have been it, but a restart worked too. Thanks.
