Radeon 9600XT is turning my monitor off!

Hi, I have just brought a new PC and built it myself and I am having problems with the graphics card. First I turn the monitor on and it comes on fine but when I then turn the power to the computer on the monitor switches off!

I know that the monitor works fine and that all the components apart from the Radeon 9600XT are properly fitted. I have used an old PCI graphics card to test the computer and it works fine, so the only problem is the Radeon 9600XT that is in the AGP slot.

I have no idea why it is turning the monitor off, can anybody help?

Here are the specs if it helps:

Foxconn 600A01-6LRS Motherboard
Radeon 9600XT 256MB (8xAGP)
350 Watt Power Supply

Thanks :)
 
It is a Hercules 350 Watt PSU (PX-350) brand new

I have just read something about installing AGP drivers, should I install Windows first or should the graphics card work straight away after building the computer and turning it on for the first time?
 
Your graphics card will work before windows installed, so try installing the latest Catalyst drivers and chipset drivers.
 
yeah, unfortunately, also if you had pci or integrated graphics in your mobo, make sure they were disabled before inserting the agp card
 
Well, I have installed windows and AGP drivers using the old PCI graphics card but the new AGP graphics card still causes the monitor to turn off whenever I try to turn the computer on.

I have run out of ideas. What could it be? :(
 
This is what it says on the side of my power supply:

Hercules PX-350 (350 watts)

AC Output
220V 3A 50HZ
110V 6A 60HZ

DC Output
+3.3V 18A
+5V 25A
+12V 12A
+5VSB 2A

Is it powerful enough?
