When I insert my 3G Vodafone Data Card (Novatel U630 Huawei modem) into my desktop computer (I have a PCMCIA card), it freezes my pc and makes a "beeeeeeeep" sound. I have tried everything I could think of. Even uninstalled & re-installed drivers. My pc runs on Windows XP. Please can someone help me with this error. I'm not phoning the Vodacom help line as my dog knows more. (Have tried them on a previous occasion). Please!!
