NEED HELPZOR K8N PRO MOBO!

[efript]

Ok, i just built my own computer for the first time, it includes a athlon 64 3200+, a gigabyte k8n pro mobo, a nvidia fx5600 ultra, a gig of ddr memory, a cdrw/dvd drive,a seagate barricuda 7200 rpm SATA drive, a maxtor 120gb. so the problem is that when i boot up i get a device not found for the SATA drive, but then i try booting off the cd, it goes into the xp setup, i press f6 to install other drivers for my SATA drive, i copy the correct files from the cd to the floppy, and isntall them from the floppy, but then i get an error at the setup is starting windows screen. so you guys, can you please help. ive tried messing with the bios and stuff, tried a new xp cd, and made sure everything was connected properly, but to no avail. so what do you guys think? any suggestions are greatly appreciated. o and i know im posting in the wrong forum but this is the quickest way to get help (the local pc store wanted to charge me 80 bux to look at it...).
