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,

    Since they are the same check both ASUS and Intel for installation instructions. Usually their sites would

    offer install help and some in the .txt or other files included in the download file.

    The troublleshooters you need are in the replies above and Command Prompt commands will only help

    in the cases indicated, such as using an Elevated Command Prompt to run SFC /scannow. What you

    are thinking as DOS, now Command Prompt, have very limited functionality and offer little help in this

    case.

    Hope this helps.

    I am wondering, since my access is limitted to a command prompt... What helpful troubleshooting information can I extrapolate using Dos commands (if any)?

    Hey Rob~

    I havent got any feedback from ASUS as of yet. Only text document in the download was a license agreement. I have reviewed the forums there (ASUS) but, havent found any info to help. I did review the troubleshooting section they have but, it was of no result as it serves to assist with hardware problems... and I dont have those problems... mines a software (driver) problem.

    I did goto Intel and have verified that they are offering the same IMSM version (V8.9.0.1023). oddly enough... the one at ASUS is dated 4days later tho!?! (Im thinking insignificant).

    :-) standing by~

    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.

    Hey Rob~

    Thx for all your help so far~

    I submitted a tech assist to ASUS (re proper install) and am waiting for a response~ I'll post it here as well once I get it~

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