Computer shuts off after a few minutes of use


My iMac (early 2009, 24") started shutting down after a few minutes of use. It's not a clean shut down. It's an instant cut-off of power.

Using Hardware Monitor, everything looks normal except with the Northbridge...

- The voltage sensor always shows 0 volts.

- The current shows 0 as well.

I've tried resetting NVRAM and SMC, but that hasn't helped.

Does anybody have any advise before I replace the system board?

if you haven't already i would try cleaning the dust out, make sure the fan is still spinning, it sounds like a possible overheating issue

Thanks Michael.

Overheating was the first thing I thought of. I tried all you suggested.

I also tried using smcFanControl to increase the fan speeds. I replaced the thermal compound on the Northbridge as it was running a little hot (about 75 degrees C at idle). It now runs about 5 - 10 degrees cooler. Everything else seems to be running cool.

So far, nothing has helped.

Best to take the frame off and take a look at the diagnostic lights when it goes down. That will tell us where to look.

Thanks Mayer. I did that too. It goes directly from 4 lights to 2. Unfortunately that doesn't help.
