This has been happening to me too for the past few weeks. At first Eric had me running tests on my RAM, insisting that I had bad memory. All those tests passed, and every time my computer locks up like the way Wrao just described, it is when iTunes is running and playing a song. It doesn't matter which song either, it just eventually happens. I suspect Console might reveal something if you check it after the crash. I've failed to do this.
It is with great regret that we say our farewells to Jack, who passed away on May 28th, 2005. Jack, you will be missed by all
