I installed a retail windows 7 onto a new build (pentium G4600/GIGABYTE GA-B250M-DS3H. The Mouse and keyboard was working at first and I have them plugged into usb 2.0, but I couldn't connect to the internet. I'm guessing because I needed a LAN driver. So I installed everything on the cd which came with my motherboard, Once the cd finished installing it asked me to restart the pc but at that point the keyboard and mouse was not responding so I couldn't select the relevant button to restart. I reset and switched off the pc but no luck. Anyone have any ideas? If worst comes to worst ill try installing windows 10 as that should fix all the issues. I appreciate any help you can give me, thanks
