It's possible that one or more of your services has been disabled. Go to Start, Run, and type in services.msc. Check to see if the following services are running, Event Log, Remote Procedure Call (RPC), and Windows Managment Instrumentation. (Event Log and Windows Managment Instrumentation can be set to Automatic and RPC to Manual. Right click the items to start them and choose Properties to alter any settings.)
Finally did a System recovery using the Toshiba recovery disc on my laptop (as it was Fri pm all was backed up for the weekend) and all was put right, there were one or two other things not working correctly, including the network part of Control panel and the status icon for wi fi at bottom of the screen, anyway we are all sorted now, Thanks to all who contributed.
