Unity Weird Graphics Error

Hello, I'm not sure if this is a unity problem or if it is a problem with my computer's graphics card or what. But as of late (meaning 10 minutes ago) Unity started giving me these really weird dots on my sprites. I'm on a new computer so I don't think it's a problem with its card? I've never had any problem like this with Unity in all my time using it. It's only happening in Unity. Here is an image of what I'm talking about: http://i.imgur.com/ZX2vGkB.png Sometimes the dots or whatever are different shapes, sometimes it affects all the sprites, and sometimes, when in game mode, it affects the whole screen. The only thing I can do to reproduce it is switch to another program for a minute or so and then un-minimize Unity, If it is in play mode it will be the whole screen, else it will be just the sprites. I've tried to turn off Anti-Analyzing, but it has no effect. Any ideas??
