So, I just built a PC with windows 8.1 (yes, 8.1) and I can't connect to the internet because I don't have the drivers for my network adapters, and when I try to Install drivers, wether I've downloaded them using another PC, or picked one of the ones on the computer already, it just says "The system cannot find the file specified". But, I don't think the drivers need to be installed, Because the device manager error code says "windows cannot load the drivers" not "Drivers are not installed" pls help
