    Everynow and then randomly my pc freezes and essentially shuts down, whatever screen I am on it is still there but when I push the power button it reboots.
    I checked the temp, and it is running around 55, 1 out of 10 I will get the blue screen but it goes away before I can read anything? What info do I need to provide?

    Intel D946GZIS mobo
    2gb Kingston Ram
    Pentium D processor 3.0*2
    500g wd hdd.
    Also I get no error and it boots back up as if I shut it down.

    You can read this and learn how to get and debug a minidump of the system when you get the dreaded BSOD.

    Please read and follow all the directions before doing this. As there are many steps that rely upon each others info.

    The pool is already corrupt at the time of the current request.
    This may or may not be due to the caller.
    The internal pool links must be walked to figure out a possible cause of
    the problem, and then special pool applied to the suspect tags or the driver

    This is what I got so is win32k the problem?

    Not the problem but it is an indicator of what might be going on.
    It could be hardware related
    Any new parts installed recently? memorycpu,mobo etc?

    You can run a check on your memory with Memtest available here at MG's(read instructions)

    Of course before beginning make sure to backup all your info now. Better safe than sorry.
    Post back when you get a clean bill of health on the memory....

    Possibly a power supply porblem.

    If you have added any hardware that could cause it, how old is the comp? I see your running vista so leads be to believe you have a new comp unless you upgraded.

    best thing to do if you can't read the blue screen of death is hit f8- then in the advanced start up options menu select "disable automatic restart on system failure"- this stops the pc from rebooting from bsod errors- then you can read error message - you won't find the answer there but you may get a few clues - you may have to boot into safe mode if its buggy device drivers - or last known good config

    I think thats a registry problem - if "last known good config" doesn't work then you may have to rebuild your registry in the recovery console

    boot from your windows cd rom and select repair installation to get to the recovery console -on enter press 1 or 2 to select which os you want to restore then it will ask you for the administrators password - you are then in the recovery console - you'll see the prompt


    just type

    delete c:windows\system32\config\system
    delete c:windows\system32\config\software
    delete c:windows\system32\config\sam
    delete c:windows\system32\config\security
    delete c:windows\system32\config\default

    copy c:windows\repair\system c:\windows\system32\config\system
    copy c:windows\repair\software c:\windows\system32\config\software
    copy c:windows\repair\sam c:\windows\system32\config\sam
    copy c:windows\repair\security c:\windows\system32\config\security
    copy c:windows\repair\default c:\windows\system32\config\default

    hope thats helpful

    Memory is good, pc less then 6 months old. Recently added a sound card and reformatted twice since this started and yet it persists. I am going to go with whoever said PSU, or CPU. Both of which I am replacing anyways. After that I will see I guess.

    Is your machine overclocked at all, how is the memory timings are they at where they should be? Overclocked or mismatched memory or memory running at the wrong timings will cause problems. PSU is another possible cause but I'd check the BIOS check all the settings before pulling other items out. I assume you've ran Memtest? Do you have a multimeter or a PSU tester before pulling it? Drivers updated, is things stable in safe mode?

    I'd also try removing that sound card and see how things run, try with one stick of RAM then try the other, if you have another PSU try that.. but try one thing per time. You'll of course want to figure out who or what is causing it. Changing too much or everything at the same time may make it go away only to crop up again later.

    Last known good configuration is great but each time to get into windows without a problem.. that becomes your last known good configuration!

    I'd start by assuming it's a software problem until you've either established it's hardware or you run out of things to try software wise.. e.g. drivers, updates, BIOS settings etc then move to hardware troubleshooting.. e.g. remove items, change things around, test PSU.. etc
