The only thing I can think of is a 'Conflict' in the operating system with something else you have on board.
Try disconnecting the DVD /CD drive(s), and all external connectors USB's, printer,scanner etc, and try.
If this works OK, reconnect one at a time until the problem re-occurs.
You may have to un-install that devise, and re-install.
Are you running 2 or more Anti-virus programs at the same time, as that could cause a conflict.
