INTERRUPT_EXCEPTION_NOT_HANDLED
What is this error?
An exception occurred during interrupt processing that was not handled. This is a low-level CPU/driver error during hardware interrupt handling.
Common causes
- driver bug during interrupt handling
- hardware interrupt conflict
- corrupted interrupt dispatch table
- overclocking causing interrupt timing issues
How to fix it
- Update all drivers
- disable overclock
- check for IRQ conflicts in Device Manager
- update BIOS

Bug check 0x0000003D (INTERRUPT_EXCEPTION_NOT_HANDLED) is a relatively rare BSOD indicating an error during hardware interrupt processing. This is a low-level issue between hardware and drivers.
How to fix it:
- Update ALL drivers — GPU, chipset, storage, network — from the manufacturer's website
- Update BIOS to the latest version — BIOS handles interrupt routing
- Disable any CPU or RAM overclock — overclocking can cause interrupt timing issues
- Check Device Manager for any devices with conflict warnings (yellow triangle)
- If recently added new hardware (PCIe card, USB device), try removing it to test
- Run memtest86 — memory errors can corrupt the interrupt dispatch table
- Check the minidump for the specific interrupt vector and any faulting driver
- If the error specifically points to a PCIe device, try that device in a different slot
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
