Thanks for your suggestions.
I checked out the Device Manager and found that one particular section called Other Devices had a yellow question mark next to it.
I opened that up and in side this section were a number of yellow marked areas.
These included as listed
Base System Devices
Base System Devices
Base System Devices
Base System Devices
BCM2045
Ethernet Controller
Network Controller
DCI Device
SM Bus Controller
Video Controller
So I presume this is the problem, so how do we get this sorted please.
