KMODE_EXCEPTION_NOT_HANDLED

What it means

A kernel-mode program hit an error Windows could not catch.

Common causes

• Incompatible drivers
• Unstable overclock
• Faulty RAM

How to fix it

1. Open the crash dump in WhoCrashed or BlueScreenView: it usually names the driver file that caused it (for example nvlddmkm.sys is the NVIDIA driver).
2. Update the graphics, chipset and network drivers from the maker's site (NVIDIA, AMD, Intel or your board vendor), not from a driver-updater tool.
3. Undo any overclock or undervolt, including XMP/EXPO memory profiles, and test at stock settings for a day.
4. Test the RAM: run Windows Memory Diagnostic (search mdsched) or MemTest86 from a USB stick. Any error means a stick or its speed setting is the problem.
