Error codes

0x00000050

PAGE_FAULT_IN_NONPAGED_AREA

What it means

Windows looked for data that must always be in memory and did not find it.

Common causes

• Faulty RAM
• A buggy driver
• Damaged system files

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. 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.
3. 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).
4. Open Terminal (Admin) and run sfc /scannow, then DISM /Online /Cleanup-Image /RestoreHealth. Restart afterwards.
