iMac just shut off by itself

[stuff99]

So I was surfing the net and all of a sudden my screen went dark and I realized the iMac just turned off by itself...this is the new iMac and I've been using this since August and this never happened before.

I installed leopard when it first came out....

has this ever happened to you guys before?

any explanation for this?

thanks in advance!

Dumb question: Are you sure that it wasn't just the plug coming loose?
