ATTEMPTED_WRITE_TO_READONLY_MEMORY (0x000000BE)
What is this error?
A driver attempted to write to read-only memory. This is always a driver bug — the driver tried to modify protected memory.
Common causes
- buggy driver writing to protected memory region
- incompatible driver after Windows update
- corrupted driver file
- hardware causing memory remapping issues
How to fix it
- Check minidump for faulting driver
- update or reinstall that driver
- run sfc /scannow

Bug check 0x000000BE (ATTEMPTED_WRITE_TO_READONLY_MEMORY) means a driver tried to write data to a memory region marked as read-only. This is a driver bug — the driver is accessing memory it's not allowed to modify.
How to fix it:
- Check the minidump (C:\Windows\Minidump) — it identifies the faulting driver. This is the key to fixing it
- Update the faulting driver from the manufacturer's website
- If the driver was recently updated and that's when the crash started, roll it back: Device Manager > right-click device > Properties > Driver > Roll Back Driver
- Run 'sfc /scannow' to repair any corrupted system files that might be providing wrong memory mappings
- If the faulting module is ntoskrnl.exe, it's likely a secondary effect — check other events around the same time in Event Viewer
- Test RAM with memtest86 — faulty RAM can cause pages to be incorrectly marked as read-only
- Update BIOS — memory mapping is configured by BIOS and bugs can cause incorrect page permissions
When to seek help

- 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
