Problem scenario: When you log into your Windows 7 computer, you get this error:
"AccelerometerSt.exe - Application error
The application was unable to start correctly (0x000007b). Click OK to close the application."
How do you keep this error from popping up every time you log in?
Reinstall HP 3D Driveguard. You used to be able to download the media from here (http://h20564.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_124661_1). This link will likely change in April.
