Hello everyone, I'm new to this forum, I came knowing that they are experts. I'm from Argentina, sorry for my English. My problem is that my PC does not recognize the mini plate wifi nor ethernet connections, it is very rare. I've tried these three operating systems and hardware not appear in my control panel -> device manager. I installed all versions of drivers, but I have not gotten any results. I do not know what else I can do. Just thinking that something has been burned into my motherboard. I hope your help. Emachines Eme730 Regards!
