i doubt its a bad mobo or cpu, it really is rare and unlucky for one of these to be bad, and your psu looks solid,
make sure both power pins are attached to the mobo, thres a 20/24 pin one (the fat 1) and a smaller 4/6 (i think) pin one, both must be attached.
Have you got a onboard vga, if so take the graphics card out and use the onboard.
sorry about the multi posts, also try all the diff ram slots, alos if you havnt got a motherboard speaker you wont hear the beebs, i was in a simular situation a month ago, had to update the bios with a older cpu before my latest one would work, make sure the motherbord supports the cpu form an old bios, if not you may need to update it before it works
Well this system worked almost for a year. I am sure i have speaker, since i got new one from the box yesterday and plugged it in. It doesnt makes a single sound. All power cables are plugged in. RAMs tested - nothing changed.
I am not sure if i got onboard graphics card... i'll have to find out.
Looks to me like MB doesnt even attempting to start post.
oh its not a new build, you can tell if you have a onboard by cheking if theres a vga (blue) port on the mobo i/o
Nope i dont see it.
I will be probably taking MB, CPU and Memories to RMA technicians tomorow.
