HI! Here again asking stupid questions...I have a "TP-Link 10/100/1000Mbps Gigabit Ethernet PC Card" and first I installed the original drivers from the cd that came with the card and got an error message: Windows cannot load the device driver for this harware. The driver may be corrupted or missing. (Code 39) Click Troubelshoot to start the troubelshooter for this device. Ok so I click...and then i only get an empty screen... So I downloaded the newest drivers and installed them but it says still the same... So the next thing I did was /google and from there I found loads of random sites and then ofcourse Microsofts support site...so I tried it...and it says 1st: Click Troubleshoot to start the Troubleshooting Wizard. The wizard asks you some simple questions and provides a solution to your problem based on the answers that you provide. If the Troubleshooting Wizard is not available, go to step 3. Follow the resolution steps provided by the wizard to resolve the problem. Yeah! good luck...when I only get an empty window where even not the search works... So what to do?? btw...the card is installed in a "Dell Dimension XPS T550" and before that it was in my other computer and worked just fine..!
