My iMac has been giving me some trouble lately. It will randomly shut itself off. The only explanation I can think of overheating. I have my subwoofer behind it; I don't know if that produces enough heat to cause it to shut down or not.

It's also plugged in to a powerstrip with quite a few other things plugged in. Could it be taking too much power?

Anyway, any and all help is much appreciated. Thanks ya'll!

If it was taking too much power, the fuse should burn (or in case of the newer stuff, turn itself off).

So, you're saying it could be using too much power?

Well, either way, I really need to know what to do about this

i think what the other poster was trying to say was that the power strip should fail if you were using too much power, not the imac.

you could, if you wanted to, run a little test. disconnect everything else and run just the imac on that strip, or alternately, hook up to another power strip in another part of your house.
honestly though, i'd guess the problem would be on the imac side of your power cable, not the house side. is the cable tight on the imac (does it even come off, i don;t know myself). could be a power supply in the imac too maybe.

It's probably something with the machine itself, not the external power supply. If it's pulling too much power, and the fuse doesn't fail you've got lots more trouble than a faulty computer... And you should have felt it by now. To make it short, I don't think the things plugged in to the power strip are pulling too much power.

Overheating, I dunno. My iMac is running Folding at Home right now, and is constantly at 95% load, at 62C. It seems like it would take lot to overheat the machine.

Maybe the power cable isn't quite plugged in. Something may have lodged it out of place.

Ah, ok, I think I found the culprit. There was a lot of paper right underneath my iMac. One peice in particular was sitting pretty close to the vent on the underside of the computer. I'm thinking it was making it too hot.

I moved some of that stuff away and it hasn't shut down yet.

The moral of the story: Don't store stuff under your iMac!
