Okay so long story short. My desktop crashed and i got the blue screen of death. Got a new hardrive and blue screen went away. Reloaded xp install disc and I thought everything was good. However thats the only disc I used. I have a few questions. First I used a ethernet cable to hook up my router and computer but my computer wouldnt recongize it, but green lights were on? Also other laptops are connected wirelessly and works fine. Do i need to install another disc or program to use the internet?
