I have built a new pc. I'm pretty confident that everything is installed and wired correctly, but I could have made a mistake. I am trying to load Win XP Pro. I boot from my CD, it's the first boot drive. XP analyzes my system, then begins loading. I can see files flying across the bottom of the blue screen. I get past the point where you can press F2 or F6, but I never get to the page where I can select to install XP. Prior to getting to that point, the computer auto-reboots and I hear two long beeps. I have a new OEM copy of XP and am trying to install it to a Western Digital 250G hard drive with 16MB of cache. Any help would be greatly appreciated.
