Gray screen of death?

[iMarvin]

Hey guys, today when i was using my computer i got a grey screen filling my screen up saying that i need to push the power button to restart my computer.

When i restarted it i read some stuff online saying that this is caused by malfunctioning hardware, well i performed a hardware check. The extended one, and it came up fine.

Whats wrong with my computer? It's a iMac i5 3.1 Ghz with 4Gb of ram, little over a month old.

Should i be worried?

Thanks.

If it only happen once I won't worry about it

"You need to restart your computer" (kernel panic) message appears (Mac OS X v10.5, 10.6)

yeah, if it continues to happen then you may have something faulty, usually the ram is going. But sometimes it happens once in the blue moon. I had the grey screen on my mid 2010 iMac once since i bought it 1.5 years ago.
