Two strange things have happened lately: (1) My screen will suddenly go dark -- not full dark, but "glow" dark -- and I have to turn off the power and reboot before I regain control of the computer. (2) I will put the computer in Sleep mode and return sometime later to see a line of dots in the password field of the sign-in screen. When I clear the dots, a new line will start to appear. The computer is for home use and is not networked. Does anyone have any thoughts about what might be going on?

iMac, Mac OS X (10.6.8)
