STOP: 0x0000003F

Description

The system is out of memory, due to a device driver requesting more memory than is available.

This issue may appear on some older Windows versions as "NO_MORE_SYSTEM_PTES".

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

Sample Screen

utilities or disk-intensive applications.

If you need to use Safe Mode to remove or disable components,
restart your computer, press F8 to select Advanced Startup
Options, and then select Safe Mode.

Add More Memory

The operating system or application may have run out of usable memory.

Adding additional memory may solve this problem. This is especially true if your system is configured for a minimal amount of memory for Windows.

Technical Details

The system has performed too many I/O actions. This has resulted in fragmented system page table entries (PTE).

After the Stop code will be 4 hex values: {Parameter 1, Parameter 2, Parameter 3, Parameter 4}.

Parameter 1 is 0 if system expansion PTE type, or is 1 if nonpaged pool expansion PTE type.

Parameter 2 specifies the size of memory the request.

Parameter 3 specifies the total free system PTEs.

Parameter 4 specifies the total system PTEs.
