Recently my hard drive just stopped working and so I replaced it with an older one with windows 7 that I had in my older computer. When I switched to my older harddrive with windows 7 64 bit it booted up and all of my drivers installed except for my ethernet driver. I tried using my old driver disk but it did not work. It kept saying "The realtek Network Controller was not found. If deep sleep Mode is enabled. Please plug the cable." I figured that since those were drivers to my older computer it made sense that I just had to transfer them over using USB from a different computer. Under the newer MOBO that I have now.GA-78LMT-S2P. I did that but I still received the same message. I cannot connect to the internet and I have no idea how to get this driver downloaded so that I can use the Internet on my Computer. My ethernet cable is fine. No loose wires or torn. Please help me. I've also tried to uninstall it through device manager and restart the comp but it still does not work. I've tried to unplug the power cord and remove my RAM for 10 minutes as well and that also didnt do the trick. Sorry but I forgot to mention that real tek isn't on my computer besides the audio so I cannot go into its settings and turn off deep sleep mode.
