I tried to install Windows 8 but my sound drivers didn't work. So I tried to re-install Windows 8. When it came to the drive option I chose to format and install. It said there was not enough space on the disc. So I tried a Windows 7 disc and the same thing happened. I tried to delete the disc, format the disc and the same message comes up. So I tried another hard drive in the PC and I got the same message. Any ideas why this is happening?
