Resolving “STOP 0x000000CE in Dxapi.sys” in Windows XP Operating System
A device driver is a computer program that uses computer bus or communication subsystem to interact with the hardware components. Each device driver is hardware-dependent and operating system specific. However, if a device driver gets replaced by another device driver (that does not support that operating system), a STOP error message might occur. Such STOP error messages make your operating system unbootable and data inaccessible. After such situations, you need to use an up-to-date and valid data backup to completely restore the lost files. But, if there is no such backup available or it falls short of restoring the lost data, then you need to opt for advanced data recovery software.
Consider a practical scenario, where you encounter the below error message when you start your system where the video adapter has the TV tuner or video capture feature:
“STOP: 0x000000CE (0xHEXNUM1, 0xHEXNUM2, 0xHEXNUM3, 0xHEXNUM4) in DXAPI.SYS
"DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS"
0xHEXNUM1, memory referenced
0xHEXNUM2, value 0 = read operation, 1 = write operation
0xHEXNUM3, If non-zero, the instruction address which referenced the bad memory address.
0xHEXNUM4 N/A”
The four parameters within the parentheses vary, depending on the system configuration.
The data saved in the hard drive becomes inaccessible after the occurrence of the above STOP error message. In addition, you encounter the same error each time you attempt to start your system.
Cause:
The above error primarily occurs if a Windows 2000 version of a driver replaces the Windows XP version of the driver. This replacement can take place without your knowledge when you install DVD or TV tuner software or programs from an older CD-ROM that installs drivers which are not designed for Windows XP.
Resolution:
To trouble shoot and resolve the above issue, you will need to reinstall updated DirectX device drivers that are designed to work with Windows XP. However, if the Windows XP CD-ROM does not contain device drivers for your device, then you will need to take these measures:
Look for updated drivers on the Microsoft Windows Update website.
- If updated drivers are not yet available there, look on the manufacturer's website
- Contact the support for updated drivers, if provided by the manufacturer.
However, if the above resolutions fall short to resolve the issue and data still remains inaccessible, then you need to reinstall Windows XP. A clean install of Windows XP will erase all the data from the selected partition. In such situations, you need to opt for efficient data recovery software to recover your lost data. Such data recovery tools incorporate high end scanning methods to comprehensively scan, recover and restore the lost data from your hard drive. These recovery utilities serve as easy to understand data recovery applications with to-the-point documentation, self-explanatory user interface, automated recovery procedure and advanced recovery features.
