Hog iPC bugging out badly

Hello,
I had a major issue with the iPC last night. I was running lights and the first two bands who came up I had no issues with. Right as Colby Caillat came on stage, the console started bugging out badly. My cue lists started disappearing, the palattes started showing randomly created new pallates, half the buttons stopped working properly, and the lights wouldn't respond to the console unless I punched it in manually (like, fixture 1 thru 8 @ full).

At that point, I ended up pulling the DMX line so the stage would at least remain lit as the console kept clearing itself out as well.

Does anyone have any idea as to what would cause this to happen?

Thanks,
Matt
