So i downgraded to Windows 7 64bit with a Disc with ISO File with Windows DVD Tool when i successfully Logged onto my Fresh New PC, i couldnt access internet. So i went to Device Manager and all the Network Adapters (Ethernet Controller, etc) had a Yellow triangle Error Icon, i dont know how to fix this do i go to Lenovos Website and download drivers? I have a Desktop All in One, C Series, Model 440 Touch Screen All in one. 10404.
