screen goes blank...



hoi!

my question is not exactly related to QuartzComposer, but it is to 'developing with' qc..

while working on projects that use quartz-composer, coreimage corevideo etc.. every now and then i experience computer-lockups. as the music usually continues to play i asume it's the graphics-card that just crashed (if that's how you call it..).

sometimes the screen just freezes, other times the screen(s) goes black, and judging from the external monitor giving a 'no signal' message, i asume the graphics card almosty litterally 'switched-off'.
one time the screen of my powerbook started to display amazing graphics, which would usually fear the %^* out of me, but now i actually thought of making some photo's before rebooting: http:// pulsecode.org/~arri/screenart . and in one project i occasionally even experienced kernel-panics...


my question is: is this bad for the hardware?
could i potentionally 'toast' a graphics-card for instance?

i know this powerbook is rather old, but i have similair lockups on our mac pro, and don't want to risk blowing its' fx4500 ...

thanks
arri
