Help with my first home-built computer

Hi,

I built my first computer yesterday.  Everything seemed to be going well.  It boots, the fans spin, I can access the BIOS menus.  It can see all my devices.  I jammed the Windows XP disk in to get this party started and waited forty minutes for it to format the hard drive.  After that, the computer restarted itself... and never stopped.  It just kept rebooting in circles with no sign of anything having to do with Windows.  It refuses to boot from any Maxtor CD to format the drive.  The computer beeps once when I start it. 

I've tried the drive with and without the jumper, removed unnecessary components, tinkered with the boot order, and switched the RAM's slots.  I'm "installing" Windows for the third time right now.

I have a Core 2 Quad, 8800GTS, 2x2GB OCZ RAM, 200 GB SATA drive, SATA DVD burner, and a Gigabyte "GA-P35-DS3R" board.


Thanks for any help you can offer

I have Vista, would you rather I install that?

When setting up Windows for the fourth time, it recognized that there was already a Windows folder on the drive.  I said to overwrite it.  When it was ready to restart, it said setup would continue when it was restarted.  Instead, it just went back to the original boot menu from the disc.

Just adding anything that might help you guys help me :(
