INTERRUPT_EXCEPTION_NOT_HANDLED (0x3D)

What is 0x0000003D?

0x0000003D is a critical-severity Windows operating system problem. A hardware interrupt was generated, but the kernel interrupt handler threw an unhandled exception. Commonly caused by driver memory violations, faulty motherboard chipset wiring, or BIOS settings. This can also stem from corrupted device drivers (typically network or USB controllers). Use the steps below to track down and fix the cause.

Common Causes

• Corrupted device drivers (typically network or USB controllers)
• Unstable memory controller or RAM voltages
• Motherboard chipset hardware communication issues
• Outdated BIOS firmware configuration

Step-by-Step Fix Guide

• 1
  Update chipset and network interface drivers

  Begin with Update chipset and network interface drivers; it's the step that resolves 0x0000003D for the largest share of reported cases.

• 2
  Reset BIOS settings to system defaults

  If it's still not resolved, work through the rest of the steps — they're aimed at rarer device drivers instability cases.

• 3
  Run memory diagnostics using MemTest86

  If earlier steps didn't help, "Run memory diagnostics using MemTest86" directly addresses unstable memory controller or RAM voltages.

• 4
  Disable fast startup settings in Control Panel

  Try "Disable fast startup settings in Control Panel" next if the issue persists — it addresses a secondary cause.
