At first the hard drive started quickly failing (hasn't been a year since it was bought brand new) On the last day before the new HDD I went to back up some files to find out the ethernet port disconnected. I figured the hard drive was the reason (not the first time it lost information). Fast forward a few hours and have the new hard drive in along with windows 10 bootoable USB. Got it all up and running along with driver CD's installed and even went as far as installing the LAN driver manually from my MOBO's website. Still doesn't show up in Device manager. I'm worried either my PSU is unstable or the MOBO is dying.
