vertical, coloured lines

hi,

I'm getting the strangest thing happening. After restart the screen goes gray then random coloured vertical lines draw on the screen.. trying to restart by pressing the start button for several seconds doesn't help... the macbook just turns off then back to the vertical lines.. took out the power plug but that didn't help either... the only thing that got the MB back to normal was taking the battery out then back in. After that the MB restarted normally.

I have a second MB, which had the same problem today. One of the two has had it's RAM upgraded the other hasn't been openen at all. So it's probably not a RAM issue.. the only thing I can think of right now is the heat. It's over 30 deg C and the MB's seem to be running very hot... but that's just a guess.

thank's for any feedback.
