I just recently built a new computer and I got a Seagate Barracuda 250GB hd (SATA) and I installed windows vista, and everything was running perfectly until i realized it wouldn't recognize my network cards, and i couldn't find drivers. So i decided to format the drive nd put on xp pro, and during the installation it rebooted the computer nd it wouldn't go past the bios screen. after some frustration i finally decided to unplug the hard drive nd try the computer, and it went past the screen so i figured the drive was screwed up. i sent it back to newegg, and they gave me a new one. so yesterday i tried to install xp pro without the whole vista thing, and same thing happened again. now the drive is screwed, i don't know whether it's the hard drive or the installation, and i don't know what to do =\ any help will be appreciated.. thanks
