    BSOD, IRQL not less or equal


    Hello.
    I am getting a random BSOD, usually after uptime of couple days. All BSODs are related to ntoskrnl.exe
    This issue started after a fresh OS install on new SSD. System is stable under prime95 (24+ hours). Memory checks OK, too.
    Any help is greatly appreciated. Thank you

    Welcome
    Code:
    !sysinfo cpuspeed
    CPUID:        "Intel(R) Core(TM) i7 CPU         960  @ 3.20GHz"
    MaxSpeed:     3200
    CurrentSpeed: 3695
    Can you stop overclocking your CPU and see if that stops the BSOD? Also, is the firmware of your SSD up to date? Unplug any external device (Hard drive/USB stick)

    Problematic software:
    Code:
    Start Menu\Programs\DAEMON Tools Lite	Public:Start Menu\Programs\DAEMON Tools Lite	Public
    Start Menu\Programs\Free Window Registry Repair	Public:Start Menu\Programs\Free Window Registry Repair	Public
    Daemon Tools:
    Please uninstall DAEMON Tools. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7. Uninstall the software using Add/Remove Programs. Reboot the system. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

    As an alternative, many people recommend the use of Total Mounter or Magic ISO
    System optimizer:
    These software tend to cause BSOD's. The windows 7 operating system does not require these registry cleaning software. They often tune-down rather than tune-up and can wreck the OS beyond repair. Microsoft have improved Windows 7 significantly and it is much better at organising and optimising itself than its predecessors. Check this, this and this thread for evidence.

    If you feel the need to use a registry cleaning or optimisation software, most of us recommend the use of CCleaner - PC Optimization and Cleaning - Free Download but make sure you back up the registry before making letting ccleaner delete anything.
    Perform a System File Check to check the integrity of all protected Windows 7 :
    1. Click on the start
    2. Type CMD on Search
    3. Left click and Run as Administrator
    4. Type
      Code:
      SFC /scannow

    Full tutorial here:

    AVG contributes to BSOD-s. Please remove to test:

    Microsoft Security Essentials.

    Recommended from a strict BSOD perspective, compatibility & stability compared to other antiviruses/internet security software. It is free and lightweight:-

       Warning
    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.

    Disk Check on your hard drive for file system errors and bad sectors on it.

    Reduce items at start-up. Nothing except anti-virus is required plus improves the time for logging in windows.

    Let us know the results.

    Behold! Problem solved. I am not certain what did it, but my system has been stable under prime95, numerous sleep on/off cycles, etc. for 8 days with no issues.
    Excellent, thank you very much for your help.
