Repair 0x00000001 BSOD Error APC_INDEX_MISMATCH

The APC_INDEX_MISMATCH blue screen error always occurs due to an incompatible system driver. Typically, the APC_INDEX_MISMATCH error occurs when critical system drivers such as graphics, video, and audio are corrupted, corrupted, or outdated.

There are several other reasons that can cause the APC_INDEX_MISMATCH blue screen error on Windows 10 system.

In this blog, we will discuss how to get rid of the BSC APC_INDEX_MISMATCH error.

This error occurs due to a mismatch in the APC Status Index. This is a very complex error message that can appear on any Windows 10 system with an incorrectly programmed driver.

It could have the following reasons:

  • A kernel application or device driver running in kernel mode has made the thread index and asynchronous procedure call (APC) inappropriate. This is probably due to the fact that the number of processes that have entered the critical area does not correspond to the number of processes that have left the critical area. If you run the software at this stage, the system will be damaged or corrupted.
  • This may be due to new hardware or software.
  • This error may occur when a CD or DVD is inserted in the drive.
  • This error also occurs when your computer uses the Windows Vista Aero color scheme.
  • Sometimes we get this STOP error when we unlock the computer and connect to the standard desktop.
