An invalid page fault is a small memory glitch caused when a program or operating system tries to call or use a segment of computer's memory that is mapped in the virtual address space, but does not exists in the physical memory. This problem is also seen while using MS Access in Windows. This may occur due to database corruption, fragmentation, or the presence of temporary MS Access files in the system. Various other registry and system related problems may also trigger this problem. If the root cause is corruption, then you are likely to face data loss. To overcome this problem, you can perform Access Repair through advanced third-party software.

Let us consider a real time scenario. Suppose you use MS Access 2000 in a Windows environment. You may occasionally encounter invalid page fault errors when you try to access the records of a database table. This usually happens due to two primary reasons:

• 
  You experienced something unusual on your Windows system. A software application may perform a write operation on a memory area that belongs to some other program. This will cause overwriting and damage to the memory area.
  
• 
  Incorrect passing of parameters between a program and the operating system, leading to the execution of invalid instructions. This is caused due to the wrong internal program code.
  

Invalid page faults in MS Access may be cause due to many other factors. You need to perform the following actions on your database to identify the root cause of the problem:

• 
  Repair damage and fragmentation:
  

Your database may have either damaged structure or some invalid data. You can run the ‘Compact and Repair Database' command to repair corruption and also defragment the database as follows:

• 
  Close the problem database and make sure no users are currently using this database.
  
• 
  Take full backup of the database. Also backup your workgroup information file.
  
• 
  Go to ‘Tools' menu, click ‘Database Utilities', and click ‘Compact and Repair Database'.
  
• 
  Provide the name and path of the database you need to repair and choose ‘Save'.
  

If the above method fails, you can try to rebuild the Access database. To do so, create a new database, export all objects to this database, and compile the database modules.

If the problem persists, you should take help of professional Access database recovery software. These third-party tools use advanced and ingenious mechanisms to efficiently repair damaged Access databases and retrieve all valuable objects, including tables, relations, keys, etc.
