Well thank god oyu fixed it im suprised your mainboard didnt have buil in netowrk 90% of PC's within the last 6 years have it buil in.
I know, it's strange there wasn't one built in alright. To be honest the amount of problems I've seen with packard bell pc's in the past few months alone makes me sure I'll never buy one in the future. I'm not saying they don't have good makes or models but I've had and seen enought of them Sandisk
