    ntoskrnl.exe BSOD's contstantly


    Hi guys,

    hopefully someone can help with this, since the 22nd/24th October my machine refuses to boot to windows. i have checked using "Whocrashed" so i could read the .dmp files and it shows that "ntoskrnl.exe" and "Apc index mismatch" seem to be the root causes.

    I have tried a system restore in safe mod and this fails before completion, i have also ran "chkdsk" which returns no errors or bad sectors. However the memory diagnostic tool reports a hardware failure, bearing that in mind i have removed in turn each RAM module and tried booting and the computer just hangs.

    i have run the SF diagnostic tool and hope that i have attached it correctly.

    If you have any questions please let me know.

    thank you in advance (Sorry for the long post)

    Welcome to SevenForums

    Problematic software:
    Code:
    1. Start Menu	Default:Start Menu	Default
    2. Start Menu\Programs\Comodo	Public:Start Menu\Programs\Comodo	Public
    3. Start Menu\Programs\Comodo\COMODO Internet Security	Public:Start Menu\Programs\Comodo\COMODO Internet Security	Public
    4. Start Menu\Programs\Comodo\Dragon	Public:Start Menu\Programs\Comodo\Dragon	Public
    5. Start Menu\Programs\DAEMON Tools Lite	Public:Start Menu\Programs\DAEMON Tools Lite	Public
    Please uninstall the above while troubleshooting your computer. They contribute in BSODs often..

    Use the free version of Revo Uninstaller in advanced mode.
    Remove Daemon Tools, sptd.sys is known to cause BSODs!

    Recommended antivirus program for Windows 7 based on stability compared to others:-

    Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

    Run a full scan with both (separately) once downloaded, installed and updated.

    Run the System File Checker that scans the of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

    Run Disk Check on your hard disk for file system errors and bad sectors on it:

    For monitoring the heat/celsius of the system, use Speccy or HWinfo:

    Upload a screenshot of your hard disk using crystal disk info:

    Look for an update on your BIOS version:
    Code:
    BIOS Version/Date	Dell Inc. 1.4.1, 07/05/2007

    Hey KoolKat77,

    Thanks for the help, i have some feedback already.

    When i try to run the sptd.sys "uninstaller" it tells me there is "No SPTD version detected" and the only button i can click is Install, which prompts for a reboot. After a reboot i get 4-5 bsod's before i can boot to safe mode again.

    Also when using the REVO uninstaller, when i am unable to locate a Deamon tools install, and also when i select Comodo to uninstall the REVO software tells me i cannot uninstall in safemode.

    Thanks again

    If Daemon is uninstalled from control panel, no stpd is there, its okay.

    Follow Troubleshoot Application Conflicts by Performing a Clean Startup and then try booting to normal mode.

    I should also mention that when i run SFC it stops at 18% and 2 out of 3 times bsod's or tells me "Windows Resource Protection could not perform the requested operation"

    I have yet to try the steps for a clean startup.

    Can you tell us the age of all the hardware of the computer and when you last performed a clean install on it?

    I purchased it in 2007 direct from Dell, it came with XP. I purchased new RAM and a 1Tb WD hard drive through Dell last christmas and also upgraded the OS to Win7 x64.

    I did a full clean about 9 months ago, I've had no problems since then until the 24th of October.
