Thanks Cocunutty,
I'm pretty sure the infinite loop fix is what I need to carry out, however I can only get as far as....
Right click-mouse over My Computer
Properties
Hardware(Tab)
Device Manager(button)
Click [+] next to System devices
.....Here as CPU to AGP Controller doesn't seem to be listed on the system devices list. Now I'm really confused !!
right-mouse on CPU to AGP Controller (or whatever your controller is called, mine was SiS AGP)
Update Driver(button)
Select Install from a list or specific location (Advanced)
Next(button)
Select Don't search. I will choose the driver to install.
Next(button)
Select PCI standard PCI-to-PCI bridge
Next(button)
Finish(button)
Reboot.
