Help! Can't Install XP Pro, Media Center, Win 98 or Ubuntu!!!!

Alright, I've built this system from scratch. Was having issues with the Bios but finally got it working on that end.

NOW the problem is that trying to install the OS. I originally tried to install XP Pro Media Center, but it kept getting stuck trying to load the drivers. I then tried XP Pro, same thing. I went to Win98 to see what happens, same thing. So I decided to pull one stick of ram, same thing. Pulled both stick and installed 128mb from a working machine. Still getting stuck. Pulled the 40 gig WD hard drive and replaced it with a 120 gig Maxtor. Now at least it was going to the setup of the Partitions.

So it would format the drive and partition it with no issue. It tries to copy the files it needs for Windows and the freaking thing just reboots. Tried it with Win98, same thing, reboots when trying to install the OS.

Got sick and tried of it and decided to try to boot off the Ubuntu live CD to see what happens. It brings up the selection screen of what Ubuntu I would like to boot, I select the first one, then the system just reboots. Tried different selections of Ubuntu (Safe Mode, Expert Mode, etc...) and it just REBOOTS!!!!!!

Please help me keep my sanity.....
