Has this setup ever worked? Or did you just build it

its been working for a year now with no problem .. i just replaced 450wt psu with 620 one .. last time pc was on i was playing game and lights went out but my pc is backed up with ups so it dint shut down or anything so i closed the game and shut it down as usual .. but since then its not starting

So it stopped working just after you changed out the PSU?

nope... its been a month since i changed psu .. and i tried to start is with my old 450 psu still nothing

Okay, a few things to try:

Boot the PC with only 1 stick of RAM in, disconnect any HDDs and GPUs ( using your integrated graphics ) and see if you can get into bios.

tried all theses things alrady but pc dosent starts no lights no fans .. just the green light on motherboard ... but if i disconnect motherboard power supply and start psu manually using pin everything starts

You can get into windows after reconnecting the power supply and starting it manually?

nope ... my pcs isnt starting at all ... bios setting and windows are things to worry when my pc will start .. i might have confused you with saying everything starts .. starts means just fans starts to spin and lights show of

Okay, seen as you have tried different PSUs and none of the other steps have worked. I would be inclined to say that the motherboard is no longer working.
Do you have anything else you could try the CPU from your current motherboard in?
