Missing Drivers for Windows 8

Hello everyone, 

i wasn't sure if i should post this here or in the Alienware section so my appologise if this is the wrong section.

Recently my HDD failed and i had to install a brand new one. When i bought my PC i was given 4 discs: CD 1 The Operating system, CD 2 Drivers and Documentation, CD3 Applications and CD 4 Aurora R4 Resource DVD.

My new hard drive isn't booting up so ive been told i need to reinstall windows 8, when i added CD 1 into my PC to install windows it has loaded and asked me to place the CD i was given to install of all of the drivers, none of the CD work when i put them in to disk tray so am i missing a CD? or does anyone know how i can download the correct drivers to USB and install them that way?
