What is 0x00000037 Error?


The Windows Stop Code 0x00000037, labelled FLOPPY_INTERNAL_ERROR, is a Blue Screen of Death (BSOD) that occurs when the system encounters an internal error while accessing or managing floppy disk controllers. Though floppy drives are rarely used today, this error can still surface in systems with legacy hardware configurations or virtualisation environments simulating floppy devices. This error is uncommon in modern systems but may appear during boot-up, legacy hardware testing, or while running virtual machines with virtual floppy drives attached.

Causes

  • Faulty or Misbehaving Drivers: Poorly written storage or controller drivers may mishandle legacy floppy hardware, triggering this BSOD.
  • Improper Legacy Hardware Configuration: Misconfigured BIOS or system settings may cause the OS to attempt operations on nonexistent floppy drives.
  • Kernel-Mode Antivirus or Monitoring Tools: Security software intercepting hardware calls may interfere with floppy controller communications.
  • Unstable Third-Party System Utilities: Low-level tools (e.g., hardware diagnostic tools or virtualisation platforms) may mishandle virtual floppy operations.
  • Corrupted System Files or OS Components: Malfunctioning Windows storage subsystems may fail to handle legacy device interfaces properly.
  • Software Conflicts During Boot or Hardware Access: Conflicting software attempting to access low-level hardware resources can surface this issue.

Resolution Steps




1. Update or Roll Back Device Drivers

  • Press Win + X → Open Device Manager.
  • Focus on storage and system-level drivers—especially those managing legacy hardware, virtual controllers, or I/O interfaces.
  • Right-click → Update Driver or select Roll Back Driver if available.

2. Run System File Checker and DISM

  • Open Command Prompt as Administrator, then run:

sfc /scannow

  • Once finished, run:

DISM /Online /Cleanup-Image /RestoreHealth

  • These tools help repair damaged system components involved in hardware access and management.

3. Uninstall Problematic Third-Party Software

  • Go to Control Panel → Programs and Features.
  • Uninstall recently added hardware tools, virtualisation software, or antivirus programs that might interfere with device management.
  • Reboot the system and check if the issue persists.

4. Perform Clean Boot

  • Press Win + R, type msconfig, and hit Enter.
  • Under Services tab → Check Hide all Microsoft services → Click Disable all.
  • Go to Startup → Open Task Manager → Disable all startup items.
  • Restart to eliminate third-party conflicts.

5. Run Windows Memory Diagnostic

  • Press Win + R, type mdsched.exe, and hit Enter.
  • Choose Restart now and check for problems.
  • Allow the tool to scan and detect any memory issues that could affect hardware-level operations.

6. Perform System Restore

If the BSOD started recently:

  • Go to Control Panel → Recovery → Open System Restore.
  • Select a restore point from before the issue began.
  • Follow the on-screen instructions to complete the process.

7. Update BIOS and Chipset Drivers

  • Visit your motherboard/computer manufacturer’s website.
  • Download and install the latest BIOS and chipset drivers to ensure proper management of legacy device interfaces.
