Wedge,
Your power supply is weak. The 400W Antec Power Supply I listed above has these numbers:
3.3v - 28a
5v - 38a
12v - 18a
Max Combined Wattage 3.3v + 5v = 240W
For the future, it would be a good idea to look at getting a new power supply.
Right now, lets see if we can get the motherboard to boot.
Once we can get to the computer to boot I would like you to configure the computer like this:
Motherboard
CPU
RAM
AGP Video Card
1 Hard Drive on Primary Master
1 Optical Drive on Secondary Master
Keyboard
Mouse
Monitor
That should be enough to get your computer to install Windows without having Power Supply Issues.
Crucial is owned by Micron. It is their RAM. (You will find Micron on the list.)
Take Care,
Richard
