    Random BSOD ntkrnlpa.exe and sometimes win32k.sys


    Hey guys, I have been randomly getting BSODs now for a while, usually a few a day while doing simple things like browsing the internet or reading a pdf.

    I have uploaded the latest 5 minidumps as well as a system information file on the following link: https://skydrive.live.com/redir?resi...8BC7BFC2DD!227

    Any help greatly appreciated.

    Thanks

    I noticed that in addition to it crashing randomly during the day it always crashes during the first cold boot of the day as it logs into windows, as soon as the windows logo goes away a crash occurs. That is typically when win32k.sys is shown in bluescreenview in addition to the usual ntkrnlpa.exe

    Also I reinstalled windows a few times before this as I remember this has been an ongoing issue, though not quite this bad. A few months ago I changed video card and its location in the motherboard and that seemed to fix things for a while but now it is happening again regardless of clean installation.

    Thank you

    Can you follow this tutorial: RAM - Test with Memtest86+

    so we can rule out the memory being faulty

    Thanks

    Completed 8 passes of memtest, 0 errors.

    I performed some stress tests, results are as follows:

    Furmark: With dynamics BG, Burn in, Xtreme Burn in and Post FX after 15 mins: 92 degrees Celcius.

    I then wanted to run IntelBurnTest, but the TCase for my CPU is 71.4 degrees, while it was idling at 52 and 60 for one core, and the test required a differential of 20 so I decided not to do it.

    Instead I ran Prime 95 on the Small FFT setting. The moment I started the stress test temperatures shot up to over 100 degrees Celcius!

    Is this a possible reason for the BSODs?

    Thank you

    Cleaned out the CPU fan so the CPU now idles at 26-33 degrees celcius, which is a huge improvement. Tried running IntelBurnTest, temperatures now going to approximately 80, and at times still shooting up to 103 degrees celcius.

    Hi James

    There were 142 times the below entry in your logs starting from 11th April 2012 till the latest...

    Event[34980]:
    Log Name: System
    Source: Microsoft-Windows-Kernel-Power
    Date: 2012-08-22T03:43:43.596

    User: S-1-5-18
    User Name: NT AUTHORITY\SYSTEM
    Computer: Morpheus
    Description:
    ACPI thermal zone ACPI\ThermalZone\THRM has been enumerated.
    _PSV = 346K
    _TC1 = 4
    _TC2 = 3
    _TSP = 6000ms
    _AC0 = 346K
    _AC1 = 0K
    _AC2 = 0K
    _AC3 = 0K
    _AC4 = 0K
    _AC5 = 0K
    _AC6 = 0K
    _AC7 = 0K
    _AC8 = 0K
    _AC9 = 0K
    _CRT = 348K
    _HOT = 0K
    _PSL - see event data.
    Thats in Kelvin ie ;

    _PSV = Temperature to start passive cooling by throttling down CPU, etc. = 346K = 72.85 deg C
    _AC0 = Temperatures at which to switch to the corresponding active cooling level. The lower the _ACx value, the higher the cooling power = 346K = 72.85 deg C
    _CRT = Temperature to start critical shutdown (S5) = 348K = 74.85 deg C

    Even though these are not very high...... is seems like the system shutdown at the critical temperature


    Could you confirm if your system is shutting why using normally ???
