Blue Screen error: DRIVER_IRQL_NOT_LESS_OR_EQUAL

original title: Another sad story of the dreaded BSOD... error: DRIVER_IRQL_NOT_LESS_OR_EQUAL ... Please advise as to best approach to remedy problem~

I guess it would be almost two weeks ago now that my wifes laptop first had the error (tech info line is as follows):

iaStor.sys - Address FFFFF8800110BF2B base at FFFFF880010C1000, DateStamp 4a287aa4.

The Laptop is a year old and has had no problems previously. I dont know all the specs but its an ASUS with an Intel Centrino and running Windows 7 OS.

Here's what I have done so far:

  1. I tried to boot system in all SAFE modes ... no joy... same error~
  2. I booted system with recovery CD and tried to to perform a restore from previous resore points (tried 3 previous dates so far) ... no joy ... same error~
  3. (after reading previous posts of others with simular problems) I booted system with recovery/driver cd and renamed existing iaStor.sys to iaStor1.sys and, then copied iaStor.sys file from recovery/driver cd ... no joy... same error~
  4. Submitting to my level of ignorance, I told my wife to take it Best Buy and have the Geek Squad Fix it... Knowing that she had purchased the extended warranty(costing $220), I thought it would certainly be covered! She reports them saying its not a harware problem, its a driver problem and it will cost $140 for them to fix it! She went on to tell me if we didnt have the warranty, the Geeks would chage $240, so we should feel better about that! lmao!!! we cant afford either ammount!  Well the Geek in question may well be very computer savy but he is and idiot in securing company software as he left his diagnostic disk in my laptop. Lucky for him, I am an honest man and I wont go and sell Geek Squad software on the black market!

*** Not wanting to loose any personal files existing, I have not completely reinstalled Windows 7... and I am really wanting to avoid that process (mostly, because figuring out how to copy everything without spending $$$ on an external is still baffling me!)  I hope that you'all can walk me through the fix on this because I cant afford any other process to getting our laptop back on-line~

Thx in advance for your help,

Ra

    Hi,

    Good move checking with ASUS, did you check the instructions that might be at the site where

    you downloaded the update? Are there any readme or other txt files in the drive when unzipped?

    Contact ASUS support should also help discover any known issues. Did you ask in the ASUS

    forums about any known issues?

    Check with Intel Downloads to see which version is there as if it is the same as from ASUS then

    the point is moot. If it is newer then I would use it since ASUStek is not likely to try to custmize

    that driver (chances are virtually zero).

    Hope this helps.

    (ps- after initial response from them I will ask them if I should check with Intel for a more recent version)

    Hi,

    Check with ASUStek Support and the documentation for the installation methods they recommend.

    Size is not important, its version and date that is.

    Also check with Intel Downloads and their support and documentation for the latest version which

    may be newer than the ASUS version.

    Hope this helps.

    perhaps nothing but...??? I dunno~

     I went ahead and used the Geeks disk since I already have it and why make a new one when you have one... right! One thing I noticed is that when I open the command prompt from that disk boot, it shows X:\windows\system32>  and when I change directory to drivers (ie  X:\windows\system32\drivers> ) and then do a "dir/p" command... there is no iaStor.sys file!  There is however a "iaStorV.sys" file.

    I already know from previous viewing (but checked again to verify) that the hard drive (C:) on the laptop has both an iaStor.sys and iaStorV.sys file in its directory (ie C:\windows\system32\drivers> )  ((things that make me go "hmmmmmm"... computer ignorance and being a pollack prolly arent helping!  :-)

    ok... so Im now looking at the unzipped download that I got from ASUS and it has 9 files... (assumablly an update program to be run from within an operating Win7 system) that are as follows:

    iastor.cat , iaStor.inf , IaStor.sys , license.txt , PNPINST.exe , TXTSETUP.OEM , 2KSETUP.INI , iaahci.cat , iaAHCI.inf

    when i run PNPINST.exe i get the following line: " The subsystem needed to support the image type is not present. "

    Q: is there some switch (added command)  I need to add?

    I also noted that the size of the downloaded iaStor.sys file is 330,264 bytes and the one in the laptop harddrive is 408,600 bytes!

    Q: is this a problem?

    Hi,

    The Recovery Disk is useful, particularly if you need to revert back to "out of the box" state

    (which removes all programs and date from the drive). However you often need the Installation

    Media to rebuild/re-install Windows if the Recovery Disk fails to work. The System Maker will

    usually sell the Installation Media cheap since you already own Windows. Added a Repair Disk

    can sometimes help repair the present install when the Recovery Disk does not.

    You can make a Repair Disk for Vista or Window 7 (they are different disks) on ANY computer

    running XP, Vista, or Windows 7 with a CD/DVD burner as the process uses no files from the

    host computer, only those from the download. Be aware you can't use the Vista Repair Disk

    on Windows 7 or the Windows 7 Repair Disk on Vista.

    If you need to make repair disks - these help repair Windows not re-install.
