BSoD on Windows 7

  1. Hello,

    I'm having a problem with my HP Compaq 6510b notebook -
    it freezes and then I get the BSoD every 10-45 minutes.
    All the drivers are installed directly from HP website on a
    fresh installation of windows 7 ultimate.

    I ran the latest memtest86+ V4.10 and there's seems to be no RAM problem.
    I also used the HDD selfcheck of the BIOS and there's no problem there also.
    I'm not really familiar with minidumps so I opened it and it said something about
    not being able to open the ntkrnlpa.exe file. I looked it up and it seems like it's
    a problem related to drivers/hardware,but I can't figure which driver/hardware it is.

    Intel Core 2 Duo T7250 2.00Ghz
    4096 MB RAM
    Intel 965GM Chipset
    Windows 7 ultimate 32bit

    If anyone can give me a hint on what's causing the problem I will
    more then appreciate.

    Thanks all.

    Ok so you have 3 files it looks like that are also causing the BSOD, they all happend at the same time.

    Files are: ndis.sys (NIC drivers), halmacpi.dll (essential windows file, to do with hardware monitoring as well as power.. and lastly, iaStor.sys (a required DELL file to do with SATA it seems..

    I know this advice gives no explanation on how to fix it, so far I have not come across anything as to how to fix it, other then possibly replacing both halmacpi and iastor, and reinstalling your NIC drivers. I would suggest a simple replacement out of the "dllcache" but I do not know where it is located on a W7 machine.

    Thanks for your reply.
    For as much as I know, MS replaced the dllcache on windows vista/7 to a backup folder in the winsxs folder.
    There's no problem replacing these files directly from the net, but I thinkt that the problem is with the iaStor.sys, which is a file used by Intel chipset to improve accessibility to the HDD, so maybe I need to reinstall the Intel Matrix Storage driver.
    As to the halmacpi.dll - I still can't figure from your link what exactly it does, but I'll keep looking for it on google- but it sure looks like it causes some BSoDs all over the world.

    Thanks for your response - i'll update if i'll have it fixed.
    For any other thoughts, please keep posting.

    No problem, sorry for not having any ideas to help fix, but thought I would share some insight on what each file is and what it does so others can see and narrow it dsown to help with a fix.
