Black screen + Kernel panic

Can anyone help me with this problem (I hope this is the right place):

I was working on my Imac yesterday until I got a Kernel Panic for the first time. It asked me to reset the computer, and so I did.

After the reset I got the black screen of death.. My Imac went on, but the screen was black, no chime and no working keyboard.

It wasn't doing anything after unplugging it, holding in the start button, unplugging it again and so on. Suddenly, after 24hours, it worked again. Everything is back to normal now.

But then I left my computer for more than half an hour and when I came back the screen was black (like sleeping mode), but it didn't react when I pressed my keyboard or mouse. So I reset the Imac again, and it's still working like it did before.

I asked for the problem report and this is what I got. Can anyone tell me if there any useful information in there? I don't wanna leave my Imac for 5 minutes and come back to a black screen of DEATH.
