Imac shutting down by itself

[axeldtf]

Today my imac did something unusual. I was surfing the net and scrolling through the screen with my mouse and my imac shut down by itself. I bought my mac back in feb and have all the software updates. Also there are no schedules in the energy saver to shut down at a specific time. I am starting to get paranoid and wonder if i should bring it in to the apple store. Is there something that could have caused this? I should mention that i am connected to a surge protector, nothing else on the strip shut off. Any help or advice would be appreciated, thanks!

Hard to say what caused it. Power glitch, overheating are just two things that could cause it. If you're not already using a widget like iStat Pro, I suggest you download it and use it to monitor the vitals of your iMac.

First check for a loose power cable. After that see if it happens again. If it does, take it to an Apple Store. If it is a problem, it is likely the power supply either overheating or just dying.

Is it shutting down (like when you go to Apple --> Shutdown) or is the power just turning off abruptly?

shutting down abruptly, i was looking at the screen and then boom, black screen. thanks for all the advice, i downloaded that widget. Just not sure what could cause this, still in my opinion a new computer
