Windows 7: Error Code: 3F0 appearing on boot

27 Oct 2014   #1

Windows 7 Professional 64bit
Error Code: 3F0 appearing on boot

Whenever I turn my computer on, I get a pop up box referencing an "error occurred."

Screenshot here.

The error says:

File: Window.cpp
Line: 44
Error Code 3F0
Message: An attempt was made to reference a token that does not exist

Does anyone know what could have caused this error, and how to make it go away?

Download and run ProcessExplorer. It does not need to be installed.

Drag-and-drop target to find an image. If you're not sure which application corresponds to which image in Process Explorer, click and drag the little gun sight icon on the Process Explorer toolbar, and drop it on any visible window to find out what process/image it is.

Once the error message is on the screen, start ProcessExplorer and drag the target icon and drop it on the error message window. It will show the process that generated that window highlighted in blue in the PE window.

Thankyou Ztruker, it was a program starting on boot that was causing the error message - uninstalling the program has now fixed the problem.
