I recently installed a new video card in my PC. The old video card was a Nvidia GeForce9600, the new card was the one my brother was using but recently upgraded, Radeon 4850. So after I installed a Radeon 4850 into my Asus p5kpl-cm, and turned it on, the ethernet port in the back didn't light up, and according to my router, had no connectivity. I assumed I must have busted it somehow and decided to buy a network card as a quick fix. I bought a D-Link DFE-530TX 10/100. Anyways, the light in the back now shows, and the router shows I have connectivity, but my computer still does not have any internet connection, I've already installed the drivers that came with the network card, and disabled the on-board NIC... what else needs to be done to get the internet working again? Thanks for any help!
