Hi, I have recently purchased a pc from a friend and have installed Vista 64bit from fresh with a formatted hard drive. When I try to connect to my router Vista tells me there are no networks to be found. In device manager there's no Ethernet listed at all?? The Ethernet was working fine before I reformatted my hard drive. I have tried the Abit drivers and the nvidia 650i SLI drivers but there is still no Ethernet on my system. I've got an Abit Fatal1ty FP-IN9 SLI and Core2Duo processor with 4Gb of ram and a 500Gb Samsung Spinpoint hard drive. Plus an 8800Gts graphics card. Not sure if it makes any difference but I've changed the power supply after the old on died recently as well? Vista has been throwing up BSOD's also, with ramdom causes, but I put that down to not being able to Update Vista as I can't connect to the internet. I have now reformatted again and installed a copy of XP professional with all the relevant drivers but the Ethenet is still not listed anywhere. Any help is most appreciated.
