This article is part of a continuing series on Blue Screen of Death errors. A Blue Screen of Death (BSoD) is the error screen you see when Windows has a major issue. It halts the PC and displays some very important information.
Depending on the error message you get, the steps you need to take are different.
IRQL_NOT_LESS_OR_EQUAL means one of two things: driver issues, or a bad Windows Service caused by a backup utility or antivirus scanner. This is a similar, but different error to the previous one we discussed, KMODE_EXCEPTION_NOT_HANDLED, so much of this guide will be familiar.
Sometimes the additional information on your Blue Screen will list the specific driver causing the problem, but this isn’t always the case.
If it does list the driver, you’re going to want to disable it. If it doesn’t list it, read below.
Disabling a specific driver is tricky, but here’s how you do it.
To track down the specific problem driver, you’ll need to run Driver Verifier, an application included with Windows.
You can then identify the driver listed and uninstall it when you log back into Windows
Next, you will want to disable the Driver Verification so it doesn’t always check on startup.
To disable a driver once you’ve identified it:
Alternatively, run Driver Reviver first, and see if updating your drivers to the latest version takes care of the problem.
Sometimes, this error will occur when a backup utility or antivirus scanner makes changes to Windows that it doesn’t like. If you’ve installed and run such an app lately, you’re going to want to reboot in Safe Mode and uninstall it. If that doesn’t work, restore to a Restore Point that’s just before you installed said app, and use a different app instead. We’ve got recommendations for reputable backup utilities as well as antivirus scanners.
Here’s a page on Microsoft’s website about this specific BSoD error. It’s pretty technical, but worth checking out if the above solutions don’t work.
