Symptoms

On a computer that is running Windows 7 or Windows Server 2008 R2, you receive a Stop error message that resembles the following:

STOP: 0x0000000A (parameter1, parameter2, parameter3, parameter4) IRQL_NOT_LESS_OR_EQUAL

After you receive this Stop error message, the computer restarts automatically.Note Not all 0x0000000A Stop errors are caused by this problem.

Cause

This problem occurs because of a race condition that occurs in the Dxgmms1.sys module. When the race condition occurs, the module tries to access an object that is already freed. Therefore, the module accesses an invalid memory address.
