There have been alot of people having problems with Nic cards under Win 7. It seems to be mostly the onboard nics.. Here is what happened to me:
Installed Win 7 on an AMD based sys. Biostar A770 A2+ MB. Everything worked. Ran udates and one was a new driver for the realtek Nic.. (At one time the onboard Nics and Sound were not 100% hardware.. They stole CPU cycles to emulate some of the functions on the NICS.) When it rebooted the nic did not work. I rolled back the driver.. it worked..
At somepoint the next day it stopped working when I started it up.. I hadnt installed much since it worked.. Runnning Diag.. it said no driver detected. I installed a d/l driver-Same thing.. This went on for a while.. When I tried to install driver it said couldnt find nic, if it is in deep sleep mode unnplug cable.. This made no difference.. I did manage to get it working once or twice in the next few days.. but it always went away if the comp went into sleep or I turned it off.
I have been doing this stuff for a while.. At some point I dredged up a problem Id had before when I booted a computer with a MP3 player plugged into the usb port.. I keep thinking about it and I remembered the one other piece of hardware I had added after installing Win 7 was a Logitech usb headset.. So I did two things.. I installed a intel nic in a pci slot, and I unplugged the headset. And wouldnt you know it.. I now had 2 network conections.. the realtek and the Intel.. I plugged in the headset back in. Let it reinstall drivers and rebooted.. Still had Intel NIC, but Realtek nic was gonzo..
I had downloaded many driver versions, used system restore.. almost reinstalled Win 7..
In summary: if your having a problem with on board anything.. unplug all devices except KB & Mouse.. everything else.. and then boot your comp again. Ther driver for the realtek nic, and the driver for the logitech comfort headset didnt play nice..
One other symptom.. I attempted to use a USB nic and it wouldnt load right either.. I dont know the exact hardware of the onboard nic but chances are good that it is a multy function chip doing all IO..
