Troubleshoot Stop 0x0000000A Irql_Not_Less_or_Equal"

If you have received a blue screen error, or stop code, the computer has shut down abruptly to protect itself from data loss. A hardware device, its driver, or related software might have caused this error.

The following actions might prevent an error like this from happening again:

1. Download and install updates and device drivers for your computer from Windows Update.

2. Scan your computer for computer viruses.

3. Check your hard disk for errors.

4. Perform Memory (RAM) Test.

The following parameters are displayed on the blue screen.


1. This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high.

2. The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.

3. If you encounter bug check 0xA while upgrading to a later version of Windows, this error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version.


To resolve an error caused by a faulty device driver, system service, or BIOS

1. Restart your computer.

2. Press F8 at the character-based menu that displays the operating system choices.

3. Select the Last Known Good Configuration option from the Windows Advanced Options menu. This option is most effective when only one driver or service is added at a time.

4. Examine the “System” and “Application” logs in Event Viewer for other recent errors that might give further clues.

To do this--> launch EventVwr.msc from the Run box or open “Administrative Tools” in the Control Panel then launch Event Viewer.

5. If you’ve recently added new hardware--> remove it and retest.

6. Run hardware diagnostics supplied by the manufacturer.

7. Make sure device drivers and system BIOS are up-to-date.

8. If you’ve installed new drivers just before the problem appeared, try rolling them back to the older ones.

9. Open the box and make sure all hardware is correctly installed, well seated, and solidly connected.

10. Confirm that all of your hardware is on the Hardware Compatibility List. If some of it isn’t, then pay particular attention to the non-HCL.

11. Check for viruses. (Run a thorough virus scan)

12. Investigate recently added software.

13. Examine (and try disabling) BIOS memory options such as caching or shadowing.
