Computer boots up, but doesn't display

[T345]

Hi,
I just built a computer, and it doesn't display, I have tried with and without the graphics card and different cables.
How can I fix this?
Thanks,

CPU fan connected properly?

Do you get any image (like manufacturer logo) on the screen briefly when you turn the monitor off/on?

You should also post the complete specs.

Hi, yes the cpu fan is connected properly. I don't get any image at all.
The specs are:
AMD Athlon 3200+
MS-7050 (some oem motherboard)
2gb of DDR333 RAM
Radeon 5850
600w Xigmatek Tauro PSU
60gb OCZ Vertex 2 SSD

Hmm, I just removed power to the GPU, and it boots fine
edit; I think the pci-e slot is damaged? I tried it with two gpu's and it boots fine without them, but not with them..

1)Do you have a second system to check the GPUs in?

2)Is there any obvious damage to the pci-e slot?

3)Does the mobo have a second pcie slot you could test the gpus in? I know it will probably not be at full bandwidth.

1) Yes, I will do that soon
2)Not that I can see
3) Only has one pci-e 1x slot, so the gpu wont fit :/
