Thank you so very much for responding. It is not often I make a stupid call to annoyances
but found that when my friend separated her scanner from the computer etc, the power
cord also discarded itself to the floor. With so many cables etc with computers
we did not see this and have been working on the problem for a couple of weekends
together. Anyway apparently it always had its own power source but we assumed it
was coming from the computer - NO. It was on the floor.
Anyway at least with your help which hasn't gone to waste we now have the new updated
drivers and all is working really really well, even by changing the BIOS settings
which we still may have had too. So sorry to bother you but appreciated you coming
to our rescue and at least it is now a happy ending even though we are red faced.
Do think the BIOS was needing to be changed but you would know that better than
us.
Thanks again and just know your information has taught us something anyway.
