My mac needed to be closed down :(

Hi all

was surfing away when suddenly my screen went darkish - was like a curtain sliding down and then on this was a message saying it needed to be closed down and I should press and hold in the power switch and then press it again to re start which it did fine.

I'll paste the, rather long, report below.

anyone any dea what was going on ? do I need to do anything ? should I be concerned ?

i chose not to send report to apple - what are folks opinions on this 0 should one send the report ?

here's the error report:

Thanks in advance

That is what is known as a Kernel Panioc attack and is usually hardware related so will not correct itself. Try booting from disc one of the original system install discs which came with your computer, whatever it is, and hold down 'D' and run in the extended mode.

thanks for that
