Blue Screen of Death: DRIVER IRQL_LESS_OR_NOT_EQUAL error

The Blue Screen of Death (BSOD) is a common error that occurs in Windows operating systems. One of the most common BSOD errors is the DRIVER IRQL_LESS_OR_NOT_EQUAL error. This error usually occurs when a driver tries to access a memory location that it is not authorized to access. This can happen due to a variety of reasons, such as outdated drivers, corrupted system files, or hardware issues.

If you are facing this error, here are some steps you can take to fix it:

1. Update your drivers: Outdated drivers can cause a variety of issues, including the DRIVER IRQL_LESS_OR_NOT_EQUAL error. To update your drivers, go to the manufacturer’s website and download the latest drivers for your hardware.

2. Run a system scan: Corrupted system files can also cause this error. To fix this, run a system scan using the built-in Windows tool called System File Checker (SFC). To do this, open the Command Prompt as an administrator and type “sfc /scannow” and press Enter.

3. Check your hardware: Faulty hardware can also cause this error. Check your hardware components, such as your RAM, hard drive, and graphics card, for any issues. You can use diagnostic tools to check for hardware issues.

4. Disable overclocking: Overclocking your hardware can cause instability and lead to BSOD errors. If you have overclocked your hardware, try disabling it and see if the error goes away.

5. Perform a clean install of Windows: If none of the above steps work, you may need to perform a clean install of Windows. This will erase all your data and programs, so make sure to back up your important files before proceeding.

In conclusion, the DRIVER IRQL_LESS_OR_NOT_EQUAL error can be caused by a variety of reasons, but the above steps should help you fix the issue. If you are still facing the error, you may need to seek professional help.
