For some reason my MacBook's screen flickers from time to time, just randomly. It'll be fine for a while, and then do it a little, and then stop... If the brightness is at full, it flickers darker, and if the brightness is low, it flickers a brighter screen. It doesn't flicker intensely... just a couple light flickers in a random way. It happens both on AC power and battery power. Any ideas?~! update: Okay yah, it's doing it a lot right now. I have the brightness on lowest, and it seems the right side of the screen is lighting up a lot... it's driving me crazy.
