OK, I see possible faults here:

1) Graphics card dead/faulty
2) Powersupply insufficient or faulty.
3) MB dont work with 3 RAM - remove 2
4) Have you connected ALL the nesesary power connectors from the PSU to the MB (Check your manual)

I think either one of the above would create the problems you have.

Can you test the GF card in another machine/Do you have another GF card you can try?

Got this from my friend:
1) Only connect: MB, CPU+fan+Video, 1 RAM.
2) Remove all external connections exept keyboard
3) Remove all connectors from MB to leds, buttons infront
4) Remove powerconnections from powersupply to MB
5) Try and start the PC using the MB connectors (Will not start, but to reset all components on the MB)
6) Move the reset jumper on MB to reset BIOS
7) Remove battery for 10 min - then put it back.
8) Move the reset BIOS jumper back
9) Reconnect power to MB
10) Try and boot

Hows that?
