I'm not kidding! No kernel panic or anything like that, just complete system failure. I just downloaded this app called X-ray to zap some pesky files that have been hanging in my trash since forever (It worked by the way, unlike alot of other things) Anyhow, when I was gleaming with joy after a successful delete and ready to have some wine and cheese, BAM, Finder was unresponsive, oh ok, np, Ill just restart it....nope...then iTunes failed, then Fire, and then I simply got to the pale blue screen and the spinning ball of death. I put it to sleep, woke it up...nada, so I just force-restarted it (I ahve a DP 450, so the little triangle on the front) and it booted up just fine, but there goes my 15 day uptime! Besides from this one kernel panic, this is the only crash I've had, wonderful stuff. I'm just posting this because most of the other crashes are kernel panics, and this wasn't, so there you have it
