This one is pretty scary and has me worried. It doesn't happen often but occasionally when I open a movie or a game, the framerate on my screen slows right down to a kind of stop-start stutter, and my speakers let out a kind of whining screech tone. Anyone run into this? Any idea what causes it and if there's a more permanent cure than restarting?
No apps opened. I've had this happen on games by 2 different developers and on about 3 different movies. I've had it happen during middle of day and also right after fresh bootups.
