I finally reformatted my computer and everything has gone okay except that my network adapter won't connect me to the internet. I hve Win 7 Home Pro 64, Gigabyte mobo, 8 gigs RAM. I use an ethernet cable from the U-verse modem for my connection. The device manager indicates that
the Realtek adapter won't start. I installed all the mobo chipset drivers. No go.I'm stuck.The cable works on my laptop, so it's not the cable.
Boy, I'm tired! Next step is to buy a USB wifi device if I can't find the solution.

Thanks
