"Stop error code 0x000000EA (THREAD_STUCK_IN_DEVICE_DRIVER)" error message when you run video-intensive programs


When you run a video-intensive program, such as a movie or a video game, you may receive one of the following stop error messages and bugcheck information:

STOP 0x000000EA, (0x81774538,0x81a8fc78,0x8193e490,0x00000001)
Note that the four parameters after the stop code may be different.


This problem occurs because your computer has an Nvidia video card installed that uses the Nv4.sys video driver.

To see if your system is using one of these drivers use the following procedure:

  1. Open Device Manager.
  2. Under the Display Adapters icon, click to highlight the display adapter, right-click it, and then click Properties.
  3. Under the Driver tab, press the Driver Details button to view the driver names.
  4. If you have multiple display adapters, repeat these steps for each adapter.

If you have multiple Adapters in your system, it may be necessary to capture a memory dump and have it analyzed by Microsoft Product Support to determine which video adapter driver is at fault.


To resolve this problem, obtain an updated driver by contacting your video card manufacturer, or visit the following Nvidia Web site:
