The first time this happened, I was waking my computer from sleep, and it only lasted about ten seconds, so I wasn't overly concerned about it. I just thought that maybe it was in the middle of doing something when I woke it up. Well it just happened again when I woke it from sleep, and lasted about 10 minutes. So, now I'm starting to worry. Has anyone ever seen this before, or know what this is? Sorry, first pic didn't load, look down below.
