Hi
I think you missed some wires, eg the cpu power cable, its usually yellow and black, its next to the cpu heatsink.
Or make sure that you ram is connected well and lastly check that you processor is locked well...
Oh, i have forgotten, is you mobo an ATX with 24pin or 20pin?
if its 24pin, make sure that all the power connectors are all in and well fitted..
Hope that helps.

 

I agree, do this and check back with us. thx

 

You didn't happen to use the wrong type of fan did you? Did you use a 3 pin case fan instead of a 4 pin CPU fan?

 

yeah checked it all and it is 20 pin

 

it is the right fan i know thanx btw

 

i think sumthing must have happened when i removed all the wires from the motherboard and then put em back

 

Ok the other reason that can cause a board not to start is when it detects a short circuit, so i think try removing it and test it from a clean wooden or glass table. if that works then make sure you put that material that come with it, its sort of plastic sponge and its usually pink...
Let us know what u findout after that.
