If this is the first time you ve seen this Stop error screen restart yor computer.If this screen appears again,follow these steps:
Check to make sure any new hardware or softwart manufacturer for any windows updates you might need.
If probmlems 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
