New build won't boot with GPU

[ruskle]

I'm attempting my first ever build, which has been beset by problems. When I switch on I get debug code 34 on the mobo (CPU post memory initialisation) and no signal to the monitor. I have taken off the GPU and I can now get into the bios, although code 34 still shows on the mobo.

So now I'm in the BIOS but haven't installed the OS yet. What should I do????

System details are below.

I've just gone and bought another graphics card and it still doesn't frickin work. Any suggestions please.........
