I bought Asus P5KC motherboard with intel Duo core E6750 LGA 775 and Mushkin 2x 2G Xp2-6400 4-3-4-10 Memory. I connect everything, i can start computer , i can get to bios and change settings but for some reason when i enable boot from cd-rom/dvd-rom to install windows , then i'm getting this : "Reboot and Select Proper Boot Device Or Insert Boot Media In Selected Boot Device And Press A Key" I don't know what's wrong with it, windows cd is already inside of dvd-rom. I used to isntall windows xp on my previous DFY motheboard so many times and never had this problem. Any help? Bytheway i'm using IDE cable for dvd-rw and serial ata for new not formated yet hard drive.
