— Albert Schweitzer

A blue screen of death (BSOD) is a common operating system error. When users get this problem for the first time, they are very worried that their computer has seriously malfunctioned. This is because the computer restarts immediately after it displays a BSOD. Let me assure you that it is not as big an issue as it seems, and we are here to help you find the root of the error and solve it. So that you will not encounter a BSCOD again in the future, and even if you do, you will be able to solve it without much difficulty.

There are various types of Blue screen of death errors:

• 0x000000ED (UNMOUNTABLE BOOT VOLUME)
• 0x0000007B (INACCESSIBLE BOOT DEVICE)
• 0x00000024 (NTFS FILE SYSTEM)
• 0x0000007E (SYSTEM THREAD EXCEPTION NOT HANDLED)
• 0x0000008E (KERNEL MODE EXCEPTION NOT HANDLED)
• 0x00000050 (PAGE FAULT IN NONPAGED AREA)
• 0x000000D1 (DRIVER IRQL NOT LESS THAN OR EQUAL TO)
• 0x000000EA (THREAD STUCK IN DEVICE DRIVER)

These are the errors that appear on a Blue screen of death depending on the source of the problem. These messages will help you easily identify the problem.

In this article, we will be focusing on the BSOD code D1 in Windows 7, i.e. error 0x000000D1 (DRIVER IRQL NOT LESS THAN OR EQUAL TO). Usually, the computer shuts down immediately after the blue screen of death to protect the system from further damage. This is also troublesome because it prevents you from reading the exact message of the error. Therefore, you can’t diagnose and fix the issue. I will show you how to disable the automatic restart in the following steps below:

1. Right-click on My Computer.

• Select Properties in the pop-up menu.

• Click on Advanced system settings.

• This will open the Advanced tab.

• Now under the Startup and Recovery section, click the Settings button.

• Under the System failure section, uncheck the “Automatically restart” option.

• Click OK.

Now if the error occurs, your computer will not automatically restart. If you cannot boot into Windows after this procedure, try booting into Safe Mode using the following steps:

1. When your computer restart, press F8 before the Windows logo appears.
2. Select “Safe Mode” using the arrow keys from the boot menu.
3. Then press Enter.

Before we begin talking about the solutions, we need to first answer the question what is the bsod code d1. Usually, the 0x000000D1 (DRIVER IRQL NOT LESS THAN OR EQUAL TO) error is the code used to denote problems with:
