Apart from the obvious:

1. Not all electrical connections have been made
2. Not all components have been installed correctly
3. One of the installed components are defective

I don't know how we can help you with that little information.

everything was plugged in and components installed correctly at a computer shop and service, they are good and i trust them , and i was there to see , so nothing wrong , the motherboard is working tested with 2 different cpu's , same story with the ram memories , video card working , power source working , one of my friends told me that when you buy a new cpu 4th generation with haswell you need to update bios with another haswell , or the motherboard won't recognize the cpu , is that true ? i need another haswell for bios update ?

Then it is highly unlikely that you got 2 defective CPUs in a row. However, omitting facts like that is part of what makes it hard or impossible to advise you with any specific and concrete advice.
