Hi! My PC detected some errors this past few days and kept on shutting down. It didn't work normally that I decided to reformat the hard drive. After I installed the OS i couldn't install the other drivers(audio,video drivers,etc). Some message displays "RPC server unavailable" when i tried to install 'em. Tried to connect to the internet but it doesn't seem to work either. Im using broadband and I honestly don't know how to get it back to work. Your suggestions would be highly appreciated. Thank you.
