    Question

  • Hi

    Got a PC at a clients that has just been installed and has Win 7 Prof x64.

    The machine now shuts it self down twice a day and comes up with the following Kernel-Power errors: Event 89

    ACPI thermal zone ACPI\ThermalZone\THRM has been enumerated.            
    _PSV = 323K            
    _TC1 = 4            
    _TC2 = 3            
    _TSP = 6000ms            
    _AC0 = 323K            
    _AC1 = 0K            
    _AC2 = 0K            
    _AC3 = 0K            
    _AC4 = 0K            
    _AC5 = 0K            
    _AC6 = 0K            
    _AC7 = 0K            
    _AC8 = 0K            
    _AC9 = 0K            
    _CRT = 398K            
    _HOT = 0K            
    _PSL - see event data.

    and the Error 26, Kernel-Processor-Power

    Processor 0 in group 0 exposes the following:

    1 idle state(s)
    4 performance state(s)
    0 throttle state(s)

    and

    Processor 1 in group 0 exposes the following:

    1 idle state(s)
    4 performance state(s)
    0 throttle state(s)

    Not quite sure what the messages mean - is the processor over heating?  PC is a foxconn G31MXP-K mother board with Intel E5300 CPUU with 4GB RAM

  • I think if you go to Intel and read the manual for that CPU you'll find the thermal trip is associated with the CPU.

    Suggestion: Try installing SpeedFan or similar temp probe on the box and read the temps at various points in the box. See what the temp trip level is according to the CPU manual and see if they match or are close.
