My MBA has been working great until today. Since 7:00 tonight I've had 7 Kernel Panics (where the screen comes up telling me to restart). There are no other issues (no shaky graphics or anything). Any idea what this might be? It seems to happen randomly. It has happened using either Safari or Firefox and has happened even just writing a Word Document. Thoughts? I will try to run the hardware test when I get back home later tonight.
