SESSION_HAS_VALID_POOL_ON_EXIT

STOP: 0x000000AB

 
  Description  
     
 

A system device driver or video device driver has a bug.

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.

SESSION_HAS_VALID_POOL_ON_EXIT

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.

Check if you are using the latest video device driver and that the driver is correctly matched to the video adapter model.

You can use a product like Driver Genius or Radar Sync to verify you have the latest drivers and help keep all your drivers up-to-date. If you're comfortable with driver installations, you can individually find and install current drivers.
