Before it froze i was doing alot of things, and a lot of apps were running, so the stress was pretty high. Suddenly the system froze, and a grey screen appeared, ordering me to restart my computer. Of course that wasn't possible so I shut it off.
I got some crappy photo's, I'll post them just to give you a picture of what happened.
This happened before, but the last time my system didn't react the way it did now, afterwards. When playing music, there was no sounds coming from the right speaker. The left third of the screen is now slightly darker than the rest. I don't know if that's caused by the heat(which is probably the reason the system froze), but digital watches show the same effects when placed under heavy sunlight. The sounds is working fine now, and the screen isn't as dark as it was, and will probably recover.
Anyway, here are the pictures, I hope this isn't a bad thing. I read people mentioning blue screens, but this just freaked the living sh*t out of me when I saw it the first time. With windows you take these messages for granted, but with OSX I never saw anything like this, and this happened twice in the 5 months that I have this PB.

They're called Kernel Panics, which are the equivalent of BSODs on the Mac. The #1 cause for Kernel Panics, if I remember correctly, is bad RAM. Have you installed any RAM in the computer recently? if so, take it out, and see how that works. Also, try to repaor disk permissions, and.... other stuff. Check your proccesses for funky stuff.
Hope that helps!

The RAM I replaced is now running for almost 4 months, it's no Crucial(Kingston), but it's been working fine. Only under severe stress the system busts. Repairing permissions didn't show anything weird, I don't do it that often, but once a week would seem enough. I could replace the RAM with 1 gig that was in the PB when I bought it, I think I'll test it when I've got some time to spare.

That's always a good idea. To make absolutely sure that your RAM is kosher, you can always run memtest. (I'm not exactly sure how to go about doing that)
