Windows XP, 1.8Ghz, 512Mb Ram, Lucent Win-Modem. Everything was OK until I installed a new motherboard, Asus A7V8X-X SKT A KT400. I have reinstalled the driver for the modem to make it work with Windows XP. I have changed my ISP to Virgin 24seven. Initially connection was good, but now receiving errors. Error 676 The phoneline is busy. Error 718 The connection was terminated because the remote computer did not respond in a timely manner. This morning, deleted connection in set-up and then re-entered Virgin details - now works OK. Does anyone know why this unreliability is happening? Do I need a completely Windows XP compatible Modem to settle the matter?
