Hello! I have a system that powers itself off within minutes of powering on and it doesn't seem to log the event. It hasn’t yet crashed in safe mode, but it crashed when running a memory test from the windows boot screen (it made it through the first pass and almost to the end of the second pass before powering down).
Here’s the kicker: The BIOS reads the temperature as 93 to 101C, which seems impossibly high. Both the airflow and the heat sinks feel reasonably cool.
In the control panel, “Automatic restart” is unchecked and "Write an Event to the system log" is checked, though no event is written.
My presumption: The temperature sensor is incorrectly reading about 50C hotter than reality. In safe mode it doesn’t read hot enough to power down, but normal mode and memory tests put it over the edge. However, I would have expected it to power down long before it reached water’s boiling point.
It’s a PentiumD 830 (S) DC 3.0 GHz on an ASUS P5LP-LE motherboard (HP m7170n computer) running Vista SP1. BIOS revision 3.03 05/19/2005
Any thoughts on the cause or methods to diagnose it?
