No boot up no beep no power

So it just crashed on you and is now dead?

Do you have any spare parts for testing? If so, what do you have?

Have you opened up the case to see if anything is obviously broken/burned/bulging/exploded/melted?

thanks sir!!!  
yeah!!! its now dead.. and i don't know what to do.. i'm not testing yet the spare parts , and i already opened the case, i didn't see a melted or broken parts there, the motherboard are ok, also the psu, so what if the Video cared are crashed when i'm gamming!!!!
----back when i'm gamming it turned off/shut down and i smelled a smoke then i opened the case i inspect it and i didn't see some burned parts or broken parts there.!!!
\\\\thanks sir!!!!

try new power supply, if it is a dell, you need a dell compatible. Also look at mobo for swollen capacitors to replace.
