Here is a guide explaining what you should do if you’ve encountered the Windows stop DRIVER_IRQL_NOT_LESS_OR_EQUAL error.

First of all, try booting Windows in Safe Mode and then restoring the operating system to an earlier copy. This might not fix the underlying problem, but it’s a relatively quick and safe place to start.

If that doesn’t work, you should install the latest service pack. The error is often caused by third-party programs installing hardware drivers.

Having the latest Microsoft Windows Service Pack is a good way to fix not only this particular issue, but a whole host of others as well.

Another good idea would be to install device drivers for any hardware device you’ve recently added to your setup. If you don’t have any new components, check if your video card, network card or router, and any removable or external disk drives you might have are up-to-date, with the latest drivers installed.

The error is sometimes attributed to various memory-related issues, so if you’ve recently installed any new memory to your computer, you should remove it temporarily and see if the problem is fixed.

If, in this case, the error no longer occurs, it means the cause was either bad memory or a mismatching with other memory installed in the computer at the time.

If, however, there isn’t any new memory, the old components of this kind might be bad and need to be changed.

In case you’ve tried everything we’ve recommended above and the problem still persists, it’s time to try one final approach. If the error is caused by a bad virtual memory page file, go through the following steps in order to fix this:


1. First, go to Start, then Settings, Control Panel, and then open the System icon.

2. When you’re in the System properties window, click the Advanced tab.

3. Now click the Settings button you see under Performance.

4. Click the Advanced tab.

5. Click the Change button under Virtual Memory.

6. Here select No paging file and then click every OK button you see until are windows are closed.

7. Restart Windows.

8. Once again go to Start, Settings, Control Panel, and then open the System icon.

9. In the System Properties window click the Advanced tab.

10. Click the Settings button under performance.

11. Click the Advanced tab.

12. Hit the Change button under Virtual Memory.

13. Click System managed size and then click each of the OK buttons until all windows are closed.

14. Finally, restart the computer again.
