XP Crashing randomly with different BSOD

Posted on 2008-11-04

An XP Pro workstation has been crashing randomly every few days. Ive managed to capture two different BSODs so far:
1. The problem seems to be caused by the following file: win32k.sys
Technical Information:
*** STOP: 0x00000050 (0xF6CC0023, 0x00000000, 0x8f809F8E, 0x00000002)
*** Win32k.sys - Address 8F809F8E base at BF800000, Datestamp 48ce513a

2. Technical Information
*** STOP: 0x0000008E (0xC0000005, 0xBF85FB1A, 0xAF82601C, 0x00000000)
*** win32k.sys - Address BF85FB1A base at BF800000, Datestamp 48ce513a

I have attached the minidumps and screenshot of the BSODs.

Wonder if anyone can work out what's going on there.
Thanks in advance.

    Often defective memory (including main memory, L2 RAM cache, video RAM).

    The 0x8E error is nearly always a hardware issue
    STOP: 0x0000008E

    So suggest you check the RAM(s).

    Have so far checked five of your zipped Minidumps using WinDbg.  In each case the analysis shows that the problem is probably caused by "memory corruption".
    Suggest you first try >
    memtest86+  v1.70 :

    Accepted Solution

    If the RAM(s) tests ok on at least three Memtest passes this is still not absolutely conclusive.  You could then try the following >

    Reseat the RAM.   If you only have one, consider replacing it.
    If more than one, remove all but one, reboot & see if Windows still crashes.
    Downclock the CPU/RAM if appropriate, & even try another memory slot.  

    Fan(s) ok, including PSU fan ?  
    CPU temperature?  Cooling?

    Grateful for your feedback, as convenient.

    Have tested memtest86, showed no errors.
    Have updated motherboard BIOS, done another test using memtest86 over three days.
    Still no errors.

    PC hasn't crashed since. Not sure if its the BIOS update, or a time bomb waiting to go again.

    So waiting and see if it happens again..

    Thanks guys for your suggestions.

    shanghui ... thanks for the feedback, it's appreciated.
    Has it crashed since your last comment?
    If it has and there are crash dumps available, post them here & i'll take another look.

    When you feel that the issue has been resolved, would you please close the queston.
    As the questioner it is your choice on how to do this (if your machine is still stable).   Options for closing questions. Please see this FAQ,

    Seems strange that a RAM test fixed the problem, but maybe you just disturbed the RAM(s) in it's socket?  Nevertheless as the BSOD doesn't appear to have recurred in 5 months, i guess you're ok.  Thanks for reporting back.
