Bsod driver-irql + restarts

  1. hi all (first time poster here)

    i was playing WoW earlier on and the pc restarted, it fired back up fine. 10mins after firing up, i got a bsod, didnt have time to read it, the pc wouldnt fire up in normal mode so i put it in safe mode, as it had fired up fine i restarted back up in normal mode, only to be greeted with a black screen. i turned the pc off and back on after 20secs, and restarted in normal mode once again, only to be greeted by a bsod saying something about driver-irql-not-less-or-equal, after restarting again, the pc is now running again. currently running a virus scan due to the fact that i kept being taken to other sites. im attaching the minidump files hoping i might get some answers. ok i cant attach the files as it says i need permission =O, theres no admin or passwords on this pc

    OK, boot up as if you are going to safe mode and when you get the screen with the choices on select Last Known Good Configuration and see if that makes any difference.

    If still no go, (if this is a laptop remove the battery) with the power off remove all but one stick of RAM, then try to boot in normal mode, if still no good swap the sticks. I am assuming you have more than one memory stick. A few details of the PC would help, OS, make, model, etc.

    Did you make any changes just prior to it all going wrong.?

    Do you have the facility to hook the hard drive up to another PC?

    Do you have the Windows OS disc?

    ok have tried the ram no joy. and dont have the last known config option

    the pc is
    win 7
    intel core2 quad prossecor q8300
    1tb hhd
    intel GMA X4500 integrated

    all i was doing before this happened was playing WoW, i hadnt put any new hardware to the pc. software i had install a game the night before, Hospital Tycoon, and only software i have removed was something call LogMeIn, which i hadnt put there, guessing my son had tho.

    i can put the Hdd on to another pc,

    i dont have a win 7 disk or a repair disk

    Just to clarify, when you hit F8 at boot up can you get to the list of start up choices or does it crash before it gets there?

    If you can get it there use the first option for Repair, answer the questions and enter your user name and password (if you use one) and then select "Start up Repair" from the list.

    Do you have a system back up, or recovery partition?

    What is the make and model number of the PC?

    Can you borrow a copy of Windows 7. It must be the same version as you have written on your licence sticker.

    If the above doesn't work or you simply cannot get to the first menu then put the drive in your other PC and save all the important files from it, if it will let you.

    Let me know how this goes.

    ok didnt know about the f8 started up on the repair on, and then selected startup repair, no repairs needed, now im doing a system restore its taking the pc back to when i remove LogMeIn program. the pc is now re starting.

    yes i have a recovery partition

    not sure where i would find the make and model number

    dont know anyone atm with the win7 disk,

    and im really hoping i can put the Hd into this pc, but think this one is IDE and not the other one.

    OK the pc has been running for 10mins without BSOD, hmmm seems to have crashed, its not responding to anything. :(

    WoW cant be the problem, as i have played Wow for over 3yrs now with no problems, and ever since i got the pc about a yr ago, this has only just started (since last night) and i run Wow on an external hdd, so i have wow where ever i go. the external hdd isnt even plugged in atm (its in this pc which is running fine) and im still getting the bsod, only now instead of driver-irql-not-less-or-equal, its now saying technical information and the bottom bit is something ending in 9083 i believe.

    OK, see if you can boot using the F8 key to get to the list of boot options. Then select "Disable auto restart" now when it crashes it should stop on the blue screen with the error message. Post back with the error codes I only need the first set of numbers this will be something like:


    You will then need to use the power button to shut down the system. Do it a few times to see what different codes come up.

    This anti virus for flash drive may be worth running, all the instructions are included.


    If this fails, boot with F8 and select Command Prompt, types chkdsk /r (include the gap) this will check for errors on the hard drive. You could also try sfc /scannow which will fix any errors in the file system but you may be asked for the OS disc to complete any repairs.

    If this does not work then from the "Repair Computer" option after using F8 select "System Image Recovery" this should return the PC to factory settings from the recovery partition. Unfortunately if you have to use this you will lose all data from the drive. The only way to save your data, under these circumstances, is to connect the drive to another PC.

    OK code A and D1 are both related to bad drivers, but in this case most probably being caused by malware and it looks like you have a lot in there.

    You have four choices here, you can persevere with the flash drive anti virus and see if it will eventually clean you system and get it stable enough for you to save your important files to disc or an external drive. Saving to disc would be recommended so any remaining Malware cannot spread. Then use the recovery partition facility which will return your system to factory settings and wipe out any remaining malware.

    Or, try and get the system stable enough to download and run these two anti virus scanners which should insure the system is clean but not guaranteed.



    Or, go to the Malware forum of this site and let the malware experts get your system clean (recommended).

    Or, throw in the towel and use the system recovery which unfortunately will wipe the drive of all you files. If you could get your hands on an OS disc you could attempt a Repair install but that will not guarantee the removal of any remaining Malware but will preserve your files.

    Just one more option is to get the hard drive hooked up to a desktop PC using an internal spare hard drive connector and a laptop hard drive adaptor. You could then run this anti virus on it while it is dormant.

    if i choose to recover the system by the partition, would i lose the files that are on the recovery partition, as thats where all my important doc's are, including my recent scan pic, tbh thats the only file im scared to lose. also how important is it to have the OS disk for the recovery.

    thanks Zoe

    I take it you created the recovery partition using third party software and the image was taken of the whole system. If that is the case it will preserve any files that were on the PC at the time the image was done. Any other files saved in the same partition should remain untouched. As long as your recovery files are all in good condition and you have not done any incremental back ups while you had the malware you should not need the OS disc.

    ok have done the recovery thing, first time i got bsod when it said preparing the desktop, code 0x00000050 and the file was iastor.sys. second time i couldnt enter the pc name as its already there so made a new one, again got to preparing desktop and bsod 0x000000d1 and again the same file. thrid and forth time again need to choose different name and again same code and file.

    OK, it sounds like your recovery partition may also be infected and as this was created by the manufacturer it will just be a copy of the original factory installation. I am not sure how you saved any other files to this partition as it is normally locked. From what you have reported I would say you only have two choices now. Go to the Malware forum on this site or you will have to get an OS disc and do a clean install.

    You could look into buying recovery discs from HP as this will be much cheaper than buying a copy of Windows 7.

    As i had pointed out earlier if you use a copy of Windows 7 it has to be the same version that is written on your product key sticker, if the version you have borrowed is different it will not work with your product key. Vista won't work unless you have been given the product key that goes with it and it is not installed on any other PC. Whatever you have got be sure to validate it within 30 days. Furthermore if your product key is OEM then you will have to activate it by phone if installing a retail version of Windows 7.

    To be sure you erase any trace of the Malware run a full format on the whole drive including the deletion of the recovery partition.
