  • Hi,

    Since Windows system uses separated user mode and kernel mode memory space, stop errors are usually caused by kernel portion components, such as a hardware device, third-party drivers, backup software or anti-virus services (buggy services).

    Please refer to the following steps to troubleshoot the issue.

    1. Boot the computer in Clean Boot for a test.

    2. Temporarily disable all unnecessary hardware devices in Device Manager, such as Modem, sound card or external device.

    For detail steps, we can refer to the link below:

    Device Clean Boot

    3. Run antivirus program and perform a full scanning.

    Meanwhile, I would like to share with you a useful article about Bug Check 0xA: IRQL_NOT_LESS_OR_EQUAL in Windows 7 for your reference: 

    If the issue persists, please upload the minidump file (%systemroot%\minidump) to SkyDrive ( ), then share the link to me. I will be glad to assist you to analysis the data.

    Best regards,
    Della Li
