So recently i built my pc and used my old hard drive (as well as a new one) which had windows 7 on it and i do not have a dvd rom. I then booted up my new pc and my to find that i had no way to connect to the network and non of my usbs would work even the 2.0's but my keyboard and mouse would. i cant do anything and need help on what to do in order to download these drivers. my new hard drive wouldn't work as well, i dont know if that has anything to do with drivers as well. my mother board is also gigabyte B250M-DS3H if you need that info. thank you in advance
