Fix IRQL_NOT_LESS_OR_EQUAL Blue Screen
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 referenced2 – IRQL at time of reference3 – 0 = read, 1 = write4 – 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, it’s best to boot into Safe Mode and run the inbuilt Hardware Troubleshooter. Go to Settings > Update & Security > Troubleshooter.
