My Dell Inspiron 530, 4 years old, has started to hang occasionally on startup.

The Event Viewer records an Error at every startup, which says "The SupportSoft Sprocket Service (dellsupportcenter) service failed to start due to the following error:
The system cannot find the file specified."

I've discovered that this relates to a file c:\program files\Dell Support Centre\bin\sprtsvc.exe  -  and I find this file does not exist:  in fact, there is no folder "bin" at all.

Any ideas what to do?
