Hello. I recently began having trouble with my motherboard in the new pc I built mere weeks ago. The mobo in question is a MSI Z87-G45 Gaming and the issue I'm having is with the internet staying active. Ever since I built the new system when I'm on Skype or playing a game the computer will randomly disconnect from the internet. I've tested other devices and they stay connected just fine and all my drivers are up to date. I'm planning on going back to Microcenter and exchanging it for the exact same one. If I do this, will my Windows 7 64 bit OEM carry over, or will I have to call Microsoft and get a reactivation? Additionally, will I have to re-install all of my programs when I make the switch?Also, would it be a better idea to get an ethernet card and see if that works, or just go ahead with the exchange?
