How to Fix HAL_BLOCKED_PROCESSOR_INTERNAL_ERROR

The HAL_BLOCKED_PROCESSOR_INTERNAL_ERROR BSoD, also known as bug check 0x1DA, indicates that an internal error was detected in the blocked processor library. This error typically occurs when there is a problem with the Hardware Abstraction Layer (HAL) in the operating system, which is responsible for managing hardware resources and communication between the hardware and software.

That means that the bug check is typically caused by driver issues, malfunctioning hardware, or problems with the system firmware or BIOS.

How do I fix HAL_BLOCKED_PROCESSOR_INTERNAL_ERROR?

1. Update the drivers

1. Press Win + X and select Device Manager.
2. Expand the categories and check if any of the components has a yellow exclamation mark next to it.
3. Right-click on the device and select Update driver.
4. Choose Search automatically for updated driver software.
5. Follow the on-screen instructions to complete the update.

If you don’t see any yellow exclamation marks on any drivers, start by updating the critical components drivers first. Also, if you installed any new hardware components, make sure that they are compatible with your system and download the correct driver from the manufacturer’s website.

This can be a time-consuming process, so you might want to consider installing a dedicated driver updater tool that will install all the missing or problematic drivers automatically.

2. Check for hardware issues

1. Turn off your computer and unplug it.
