CAUSE
This error message can occur for any of the following reasons:
 * An unexpected event has occurred in Windows. An &quot;invalid page fault&quot; error message often indicates that a program improperly attempted to use random access memory (RAM). For example, this error message can occur if a program or a Windows component reads or writes to a memory location that is not allocated to it. When this behavior occurs, the program can potentially overwrite and corrupt other program code in that area of memory.
 * A program has requested data that is not currently in virtual memory, and Windows attempts to retrieve the data from a storage device and load it into RAM. An &quot;invalid page fault&quot; error message can occur when Windows cannot locate the data. This behavior often occurs when the virtual memory area becomes corrupted.
 * The virtual memory system has become unstable because of a shortage of physical memory (RAM).
 * The virtual memory system has become unstable because of a shortage of free disk space.
 * The virtual memory area is corrupted by a program.
 * A program is attempting to access data that is being modified by another program that is running.



RESOLUTION
To resolve this issue, identify when the error message first occurred. Also, determine if you recently made changes to the computer, for example, you installed software or changed the hardware configuration.
