Ok - I decided to go ahead with a fresh installation of Windows 7 Professional 64 bit. I had been unsuccessful with the recovery disk generation and decided to proceed with a fresh installation from an OEM version.
Three days later, I am down to one infuriating yellow bang in device manager = Broadcom USH!
I've tried very hard to find the driver to resolve this to no avail....anyone out there able to help?
Thanks boys and girls
