Yesterday I finally had all the components to build my new computer. I builded it really carefully and I even wore gloves . When i was done I tried to turn on the computer but, as I was worried, nothing happenned . No sound, no fan, no beep, nothing. I really don't know what the problem is. As far as I know, everything is well connected and nothing is missing. it might only be the power button that I pluged at the wrong place (because i don't really know where it goes) but i have some doubt on the psu. I'm absolutly not sure because of a green light on the motherboard that is on when the power supply is connected but there's nothing on the psu to tell me that it's working. I don't know if it can help but these are the components:
asus p8h61-m lx intel core i3 2120 kingston hyper x blu ddr3 gigabyte amd radeon hd6850 ocz 600adjsli-b reconditioned (that's why i think it might be broken) and some random westendigital HDD
PLEASE HELP ME
I apreciate all the help you guys will provide me.
