Okay, so I just built this rig with an nForce4 motherboard and spent the last week just trying to get the onboard Ethernet working. It never did, so I stuck a USB connection to the modem in, and fired up the driver CD, and it all worked for a bit. Then, my card started to overheat because I had the computer in a cabinet, so I moved it to a desk and plugged in an 802.11g Belkin 54mbps adapter (Model F5D7050). Then, I downloaded the updated drivers on another computer, put them on a 1GB flash drive, and installed them on the rig in question. However, during the installation (at the end, really), I got the error message "This device cannot start", so I unplugged the adapter, plugged it back in, uninstalled the drivers, and attempted to reinstall. Only to get the same error message. Any ideas? Help would be much appreciated .
