DRIVER_CORRUPTED_EXPOOL

What it means

A driver wrote into shared kernel memory it did not own.

Common causes

• Old network, antivirus or printer drivers

How to fix it

1. Think about what changed just before it started (new driver, app, update or hardware) and undo that first. System Restore can roll back drivers without touching your files.
2. 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).
3. 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.
