New pc does not boot, help is appreciated

Thank you all for your time,

I just put together a new system

- MSI P55-GD65
- Intel i5 2.6ghz
- 6G DDR3 compatible ram
- Sapphire Radeon HD5850
- MODxStream 600W power supply.

I put everything together, and the pc starts and the following happens,

- I have no video, but the videocard fan is running.
- The CPU fan runs, all the motherboard lights are on, but no bleeps.
- A system fan i put in there, runs for about 1 second then stops.

I tried disconnecting everything and when i disconnect the videocard and bootup, everything makes allot more noise,
I thought it could be the power supply but i tried with a new one and its still the same.
I also tried with a new videocard and again it's the same.

Everything is new out of the box.

If someone has any idea's, i would be very thankful.

Stijn
