Windows 8 "DRIVER_IRQL_NOT_LESS_OR_EQUAL" iaStorA.sys

    Question

  • newly purchased Windows 8 laptop

    I shrank drive C partition using the disk utility, and expanded it again

    after this, I uninstalled Norton completely

    then the laptop keeps on crashing. These are the only 2 things I did. What is iaStorA.sys and how can I get this fixed?

    TIA

  • You get a bugcheck. A bugcheck (BSOD) is a mechanism to protect your PC from damage.

    To see the cause I have to take a look at the dumps with the Debugging Tools for Windows.

    Please start the Windows Explorer and go to the folder C:\Windows\Minidump. Next, copy the dmp files to your desktop, zip all dmp into 1 zip file and upload the zip file to your public Skydrive [1] folder and post a link here.

    If you can't see dmp files, make sure your Windows is configured correctly [2][3] to generate dumps.

    If you want to analyze them your own, check those videos [4][5] and read this KB article [6].

    The iaStorA.sys is the Intel AHCI driver. Try to install a driver update [7].

    Update the driver to the latest version 12.0.0.1082, please:

    http://downloadmirror.intel.com/22595/a08/STOR_allOS_12.0.0.1083_PV.exe


    Look if this driver fixes the issues.
