I’ve recently encountered the MULTIPLE_IRP_COMPLETE_REQUESTS BSOD error while using LogMeIn Hamachi on my laptop.

Initially baffled, I dove deep into researching various fixes. Through my previous experience in solving BSODs, I found some effective solutions.

What Is 0x44 Blue Screen Of Death Error?

The MULTIPLE_IRP_COMPLETE_REQUESTS or 0x44 stop error typically occurs when a driver tries to complete an I/O request packet (IRP) that has already been completed or canceled. This leads to a critical system crash.

In simpler terms, imagine a delivery person trying to deliver a package that’s already been delivered. This redundancy creates confusion and, in the case of Windows, results in a system halt to prevent damage.


This error is often triggered by driver conflicts or hardware issues, particularly when using software like LogMeIn Hamachi. The common causes include:

  • Driver Conflicts: Clashes between two or more drivers vying for the same resources.
  • Faulty Hardware: Problems with critical hardware components, such as RAM or hard drives.
  • Outdated or Corrupt Drivers: Drivers that are obsolete or corrupted, leading to system incompatibilities.
  • Software Conflicts: Issues arising from software, notably LogMeIn Hamachi, which can interfere with system drivers.
  • Corrupted System Files: Vital Windows files becoming corrupted or damaged.
  • Malware Infection: Malicious software that can corrupt drivers or essential system files.


If you find it too complicated to follow the troubleshooting methods, try using a BSOD repair tool.

1. Preliminary Checks
