Benchtest first, test every component u have outside of the system case.
List the specs.

Motherboard: Gigabyte GA-990FXA-UD3 Socket-AM3+
CPU: AMD Phenom II X4 955 Black Edition
GPU: HIS Radeon HD 6850
RAM: Corsair Dominator DHX DDR3 1600MHz 4GB
HDD: Seagate Barracuda 7200 1TB
Case: APLUS Case CS-500 Midi Tower Black
CD/DVD: Lite-On DVD±RW Writer IHAS124-19

Everything is put in its the right place, but when we push the start button it just wont start. Then we unplugged everything and put it back in, still nothing. My quess is the case, the led light wont even light up :(
The PSU recieves electicity so its not that. Dont think the motherboard is faulty either. Any idea?

Like Kuwese said, strip it down and bench test it piece by piece. otherwise you're groping in the dark.

how do u know that the psu receives electricity?
whats the psu u have? how can u be sure that its not causing this and that it does not have enough power ?
you need to troubleshoot to know what the problem is, but stress on the cpu and heatsink connectivity a small detail can lead to this, if thermal paste was not applied properly this could happen.
make sure ur ram is not faulty remove 1 stick at a time and test. its troubleshooting test every component

Also recheck all connectors, especially the connectors from the case front, the charts are often not clear and easily confuse. These are not the fool proof connectors that can only go in one place or in one direction, reverse 2 or hold the chart backwards to the actual block and you may not realize your error.

Did you lock down the heat sink properly? Did you use the correct amount of thermal paste (except where factory heat sink already came preapplied)? Did you position case stand offs under the motherboard (ONLY just the correct number in the correct spot for your board) correctly? Did you remember BOTH power supply connectors to the motherboard?

etc.

Thank you for all your support ;)
The thermal paste was under the fan for the cpu, and got applied as I put the fan down. All power supply connectors are in place, one long one and one 8 pin.
And I do know how to put together a PC so when I got this problem it was kind of frustrating.
oh and the PSU (as I forgot to list) is an Cooler Master Silent Pro 850w
Still no use :(
Any other ideas?

Are you getting post screen? Any beeps? Any LED's on the motherboard on?
Did you remove everything except the extreme essentials? As in Motherboard, CPU w/ heat sink, and memory (you probably will also need a small beeper sometimes supplied with motherboards since many no longer are are board mounted) and listen for the beeps, Try again without the memory. Try the memory and monitor (video card only if no onboard video available) and see if it will post and go into BIOS set up. Etc. Basically starting over.

When Kuwese said bench test it, it was from experience. If you put everything together and everything works, then you may have saved the time needed to bench test each component as you added them, but when it fails to start, you need to strip it down again and start over from the basics and build it up to see where the problems begin. I myself have done this four times without any problems, but I did this knowing that if it did not work, I just might have to tear it down again. It can be a crap shoot, on one hand save maybe 30 minutes, on the other waste all of the time spent and begin over.... I think you fell into that category this time. Sorry.

Sounds like a bad PSU or Mobo. Does the fan spin on the PSU? If it does, it's probably the Mobo.

If it shows no life at all, you have a bad power supply.
