Stop 0×0000003F

The Stop 0×3F message indicates one or more of the following problems:

1. The system Page Table Entries (PTEs) are depleted or fragmented due to the system performing a large number of input/output (I/O) actions.

2. A faulty device driver is not managing memory properly.

3. An application, such as a backup program, is improperly allocating large amounts of kernel memory.

Possible Resolutions:

1. Stop 0×3F messages can occur after installing faulty drivers or system services. If a file name is given, you need to disable, remove, or roll back that driver. Disable the service or application and confirm that this resolves the error. If so, contact the hardware manufacturer about a possible update. Using updated software is especially important for backup programs, multimedia applications, antivirus scanners, and CD mastering tools.

2. The system might not actually be out of PTEs, but a contiguous memory block of sufficient size is not available to satisfy a driver or application request. Check for the availability of updated driver or application files and consult the hardware or program documentation for minimum system requirements.

3. Another cause is excessive demands for system PTE by applications. This situation is more common in server environments. Windows XP Professional provides a registry entry, SystemPages, that you can use to increase the number of PTEs allocated.
