The powersupply went to heaven

They are relatively inexpensive to purchase (get one with a minimum of 450Watts)...and before you disconnect the power leads (the little ones near the front of the motherboard), make a small diagram of how they are attached so you can reattach the new leads correctly.

You cannot turn an ATX power supply On

when it is not connected to the mobo!!!!!!!!!!!!!!!!!

There is a logic low that must be connected to pin 14 of that connector. This is done by logic circuits on the mobo.

If you jumper pin 14 to one of the black leads in the connector it should turn ON. You can also buy an adapter from CyberGuys that will let you test the supply without having to put it in a computer.

After all of my palaver, yes it does look as if your power supply has failed.

its AGP related

i assume you are using an accelorated graphics card with a new pc like you have... please make certain the moniter cable is seated firmly inside your connector .. and please make certain your agp card (video card) is seated firmly into the agp slot.. and most importantly make certain you have the onboard video setting (if any) DISABLED
in other words .. you have to tell the pc that you are using an accelorated graphics card... this is in your pc cmos menu.. which can be initiallized when you first boot your pc...try delete key tap tap tap tap as you are booting up. that should throw ya right into the cmos menu
