Just finished putting together my first build, I turned it on and installed windows 8, then i went to install the Motherboard CD (AS rock z77 Extreme 4) and the computer restarted and the screen came back blank. Now i have done a system reset hoping it allows me to access my os again. What do i need to do to install the proper drivers for the motherboard and the graphics card (sapphire 7850)? Should i just download the drivers from online or should i use the discs that came with them?
