Hi just replaced my father in law`s desktop with a dell dimension. It is running XP and everything went fine until I loaded up the BT Voyager 105 ADSL modem. Basically I got the above message on the re-boot after installing BT Openworld. Thing just refused to boot at all until I removed the USB connector for the cable modem. Once it had booted up, I re-connected the USB cable and hey presto, I got online. I don`t want to leave his pc on forever and he is an older gent who simply wouldn`t know how to get it going again from a power off position. Anyone come across this or recommend a solution - p.s. I don`t really want to have to deal with dell tech support! Many thanks Jim p.s. I did try a search for this but came up blank so apologies if this is a repeat request.
