Since netorking a 98 machine to a XP , using realtec rtl8139/810x ethernet card. Sometimes the noise which come from this card is unbearable , i thought at first it was a wire rubbing the CPU fan until i opened the box. It sound similar to when a dial up modem is connecting but all rumbled together, the only way to cure this is to reboot the machine. Any idea's how to rectiy this, is there a volume on it like a modem????
