So i just finished my first system build everything booted fine at first. BIOS shows everything my 4 gigs of ram, i5 750 processor, hard drive ect. ect. But when i finally try to load windows 7 onto my computer i get to the option where it says choose a device to install it on. My hard drive is a Western Digital SATA 320 gb (WD3200AAKS caviar blue). and my mother boards is a gigabyte p55a-ud4p. Is this a driver issue, if so my HD did not come with any CD is there another way to update it? Or is it something else? Any help is appreciated.
