    iastor.sys & internal_power_error BSoD


    Hi there,

    I'm getting two BSoD's in Windows 7...

    The first one, "iastor.sys" invariably crashes the system after a few minutes in windows. I manage to circumvent it by working in safe mode with network options.

    The second one, "internal_power_error", occurs whenever I try to reset or shut down the computer.

    I have not added any new hardware recently, I did however have a virus infection but managed to clean the system using avast!

    I have tried to restore the system to a previous stage but to no avail.

    I'm attaching the info from the BSoD app, I couldn't produce the system health report as the viewer returns an error when I open it.

    System Info:

    HP EliteBook 8540p
    Windows 7 Professional OEM
    Intel i5 M520 @2.4Ghz
    4 Gb RAM

    Any help at all will be greatly appreaciated!!

    Thanks!!

    Both of the minidumps show different causes but both list Avast as modified. I would remove and replace with Microsoft Security Essentials at least to test.

    I see the most recent version of Avast is installed; I wonder if something else is the trouble here.

    Install the latest ethernet and wireless drivers using this tool: Intelฎ Driver Update Utility
    Code:
    e1k6232.sys       Thu Nov 05 20:35:19 2009 (4AF37D57)
    NETw5s32.sys      Wed Jan 13 11:36:36 2010 (4B4DF694)
    Also, install SP1: Learn how to install Windows 7 Service Pack 1 (SP1)

    Run driver verifier if the crashes persist: Driver Verifier - Enable and Disable
