I'm having some issues with a computer shutting off seemingly randomly.

I'm thinking it's heat related, but I'm not sure.

I've installed SpeedFan so I could watch the temperatures.

As soon as I boot up, I see the following:

HD0: 47c
Temp1: 60c
Core0: 35c
Core1: 35c

Temp1 is the ACPI temperature.

The icons next to everything are fine, except for the Temp1, it's a flame.

I cannot figure out what's causing this computer to randomly shut down.

Looking through the Log files for SpeedFan, I can see that this temperature has NOT changed a single degree.

Should it be this hot?
