What is DRIVER_IRQL_NOT_LESS_OR_EQUAL Error or 0x000000D1 Error?
A 0x000000d1 error occurs when one of the drivers you have installed on your computer has become corrupted or is behaving in an unstable way. To fix this problem you can roll back your drivers, update your drivers or restore your system to the last known good configuration. If you have recently installed new drivers or new plug-and-play software, it’s very likely that the errors you are seeing are due to this.
How to fix 0x000000D1 Error?
Updating Your Drivers:
If you know which drivers you haven’t updated in a while, then the first step you should take is to update those drivers. A newer version of a driver is less likely to suffer from system instability issues the way an old driver might. Updating your drivers usually involves going to the product’s website. If you recently installed a new NVIDIA graphics card, for example, you would go to the NVIDIA website and look for their driver’s section. To update your drivers successfully you will need to know the exact model of the hardware or accessory that you recently installed and the operating system you are currently using.
1. Go to the manufacturer’s website.
2. Find the Drivers section.
3. Select your Operating System.
4. Select the model of your hardware.
5. Download and install.
Rolling Back Your Drivers:
If updating your drivers doesn’t help, you may need to go in the opposite direction. If the hardware or accessory item that is causing this issue is something you’ve been using for some time, it may be that the most recent drivers are causing the problem. This is often true if you’re using an older operating system, such as Windows XP or Windows Vista. When you roll back a driver you will be rolling it back to a prior version that you had used successfully in the past.
1. Click on the Start button and navigate to the Control Panel.
2. Open Hardware and Sound.
3. Open the Device Manager.
4. Right click on the applicable device.
5. Select Properties.
6. Click on the Driver tab.
7. Click on Rollback Driver.
8. Follow the directions.
If You Still Experience the Blue Screen of Death:
Most driver issues will be easily resolved through either updating your drivers or rolling your drivers back to a prior version. If your problems persist after you have followed these steps, it’s possible that the driver affecting your system is not the driver you last installed. You may want to update all of the drivers on your system to be safe.
