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.

Same problem here.
Resetting PRAM takes care of it but only temporarily.

I showed them my computer, and I got an automatic replacement. However, I am not expecting this to have any effect.

Same problem on mine as well as the random turning off. It went off to Apple for repair, I will post what the result was when I get it back.

You right.

I just restart my MB and the problem came back.

Not good. Got the MacBook back last night after it languished for 2+weeks with Apple. Fine last night, this afternoon the vertical coloured lines are back. Argh.

I called Apple and they told me to reset the RAM, but that afterwards they told me to change the resolution of the screen once and that the problem should then stop

Eureka, as previously posted, resetting startup disk to the Mac HD 10.4.7 from the install DVD "Startup disk.app" works!! I have done 15 perfect restarts. I do hope that is the end of it?.....thanks
