After trying to install Window 7 on this great computer, I reinstalled Windows XP as being the OS it was born with. I used Dells homepage to get the driver from, but, - the on board sound card and NIC just won´t work. error code 10.... I have tried just about all, - so now I lean to Dell experts to make this work again. PS It worked before. and, it worked with Windows 7.... BDW, why don't DELL make windows 7 drivers for this computer? It would kick a..! Did Bill Gates tell you not to?
