Fix Bugcode 0xA – IRQL_NOT_LESS_OR_EQUAL on Windows 10

 

When it comes to the hardware level, Interrupts were designed so that resource requests don’t get into a deadlock. In simple words, it is used to break a never-ending loop. The developers also designed levels to prioritize the interrupts. Its also called as Interrupt Request Level (IRQL). If you happen to see an error Bugcode 0xA – IRQL_NOT_LESS_OR_EQUAL, it means a driver has illegally accessed a memory location while NT is operating at a specific IRQL.

Fix Bugcode 0xA – IRQL_NOT_LESS_OR_EQUAL on Windows 10

IRQL_NOT_LESS_OR_EQUAL

This is a fatal driver coding error. As an end-user, there is not much you can do.

If you are a developer, your code is trying to access an invalid memory location. You can check on different parameters like memory location that was referenced, code addressed which referenced memory. The technical Parameters are:

  • 1 – memory location that was referenced
  • 2 – IRQL at time of reference
  • 3 – 0 = read, 1 = write
  • 4 – code addressed which referenced memory

In Windows 7 this issue could also occur because Power Manager opens an Advanced local procedure call (ALPC) port. However, Power Manager closes another port instead of closing the ALPC port. Every time that a power request is made, a memory leak occurs. When the leaked memory usage accumulates to a certain level, the computer crashes.

As an end-user, you can only do a few things.

1] Run Hardware Troubleshooter

If you are getting BSOD because of this, its best to boot into Safe Mode and run the inbuilt Hardware Troubleshooter. Go to Settings > Update & Security > Troubleshooter. Click on the Hardware Troubleshooter, and it should be able to fix the issue. If you have old hardware, you might have to replace in case the troubleshooter is not able to resolve it.

2] Rollback or Reinstall compatible driver

It is possible that a recent update of Windows resulted in the incompatible driver. You will need to either roll back or reinstall the driver. You could also download the latest driver from the OEM website or uninstall the update from Windows to make it work again. The updated driver might try to access a memory area which it should not.
