Think i sorted it!!!
I think it was the 'Intrusion detction' on the DEll , i had opened the case to install the Modem, every time i booted after that i got a notice on the screen that the case had been opened,, WOW. i know i opened the thing!!!!
Anyway i got a flash of insperation and went into the BIOS and disabled the stupid thing and reloaded the modem, AGAIN, and rebooted several times and no problem, YET!!!!!!!!!!!
Am i girht in my thinking about the stupid intrusion detection, screwing up the installation??
