Hello I wondered if anyone could help me.

I built a pc using these pc components:

PSU: Cacecom 500w
GPU:8600gt
Ram:Elixir 512mbx2
Motherboard:Fatal1ty f-19ohd
CPU: Intel Pentium 4 3.0GHz
HD: Maxtor 250g sata

When i booted it the fans all came on but the monitor which was plugged into the graphics card at the time didn't come off standby.
I did research on the internet and couldn't find any solutions but i got it working with the onboard graphics when the GPU isn't installed.
When it is installed i can't get the screen on from onboard or GPU and also the power switch won't turn off the pc which it will when the PCIe is empty.

#I've tried it out of the case so doesn't seem to be a short short circuit.
#Different power supply
#Differant hard drive
#BIOS update
#Installed all the newest drivers
#Turned "init dispel first = PCIe" on in BIOS
#Tried different monitor
#Different ram
#Clearing the CMOS

Not sure what to do and can't find a UK number for ABIT to ask.
Could anyone please help me here?
