Stop 0x50 or PA GE_FAULT_IN_NONPA GED_AREA

The Stop 0x50 message indicates that requested data was not in memory. The system generates an exception error when using a reference to an invalid system memory address. Defective memory (including main memory, L2 RAM cache, and video RAM) or incompatible software (including remote control and antivirus software) might cause Stop 0x50 messages.

Interpreting the Message

This Stop message has four parameters:

1. Memory address that caused the fault
2. Type of access (0x00 = read operation, 0x01 = write operation)
3. If not zero, the instruction address that referenced the address in parameter 0x01
4. This parameter is reserved (set aside for future use)

Resolving the Problem

The following suggestions are specific to Stop 0x50 errors. For additional troubleshooting suggestions that apply to all Stop errors, see the section titled "Stop Message Checklist" later in this tutorial.

• If you added new hardware recently, remove and replace the hardware to determine whether it is causing or contributing to the problem. Run Windows Memory Diagnostics to determine whether the feature has failed.
• Stop 0x50 messages can also occur after you install faulty drivers or system services. If the driver file name is listed, you need to disable, remove, or roll back that driver. If not, disable the recently installed service or application to determine whether this resolves the error. If this does not resolve the problem, contact the hardware manufacturer for updates. Using updated drivers and software is especially important for network interface cards, video adapters, backup programs, multimedia applications, antivirus scanners, and CD mastering tools. If an updated driver is not available, attempt to use a driver from a similar device in the same family. For example, if printing to a Model 1100C printer causes Stop 0x50 errors, using a printer driver meant for a Model 1100A or Model 1000 might temporarily resolve the problem.
• Check your hard disk for problems.
