Fatal Error Solutions

Plug and Play detected an error most likely...

STOP: 0x000000CA


The Plug and Play manager failed, likely due to a bug in the Plug and Play driver.

Some older versions of Windows may show the description as "PNP_DETECTED_FATAL_ERROR".

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

  Sample Screen  

A problem has been detected and Windows has been shut down to prevent damage to your computer.

Plug and Play detected an error most likely caused by a faulty driver.

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

The Plug and Play Manager encountered a severe error, probably as a result of a problematic Plug and Play driver.

After the Stop code will be 4 hex values: {Parameter 1, Parameter 2, Parameter 3, Parameter 4}.

Parameter 1 specifies the cause of the issue.

0x00000001 Duplicate PDO: A specific instance of a driver has enumerated multiple PDOs with identical device ID and unique IDs.
0x00000002 Invalid PDO: An API which requires a PDO has been called with random memory, or with an FDO, or with a PDO which hasn't been initialized (An uninitialized PDO is one that has not been returned to Plug and Play by QueryDeviceRelation or QueryBusRelations.)

0x00000003 Invalid ID: An enumerator has returned an ID which contains illegal characters or isn't properly terminated. (IDs must contain only characters in the ranges 0x20 - 0x2B and 0x2D - 0x7F.)
0x00000004 Invalid enumeration of deleted PDO: An enumerator has returned a PDO which it had previously deleted using IoDeleteDevice.
0x00000005 PDO freed while linked in devnode tree: The object manager reference count on a PDO dropped to zero while the devnode was still linked in the tree. (This usually indicates that the driver is not adding a reference when returning the PDO in a query IRP.)
0x00000008 Null pointer returned as a bus relation: One or more of the devices present on the bus is a NULL PDO.
0x00000009 Invalid connection type passed to IoDisconnectInterruptEx: A driver has passed an invalid connection type to IoDisconnectInterruptEx. The connection type passed to this routine must match the one returned by a corresponding successful call to IoConnectInterruptEx.
0x0000000A Incorrect notify callback behavior: A driver failed to preserve IRQL or combined APC disable count across a Plug 'n' Play notification.
0x0000000B Deleted PDO reported as relation: One of the removal relations for the device being removed has already been deleted.

Parameter 2 depends on the value of Parameter 1.

Parameter 3 depends on the value of Parameter 1.

Parameter 4 depends on the value of Parameter 1.
