Hi guys,
sorry if im posting in the wrong section, this is my first post.

I got around to buying all the components of my new build;

i5 4690k
Asus Z87-a
antec truepower classic 650 watt
Gigabyte 780 GTX 3gb
Kingston HyperX predator 8gb RAM

put all the parts together, but the system won't start up. so i 'breadboarded' it, to try and figure out what's wrong, and still nothing. When I boot it up I get a 'no signal' on the monitor.

At first, I thought it was a faulty mobo, so i went back to return it, however, the guy tried it at the store on a different cpu and it worked finely. so this ruled out the mobo. Then i tried my cpu on an Gigabyte mobo and an Asrock mobo and none of them worked.

before I go and head back to return my cpu, I want to make sure im not making any noob mistakes, I haven't built a computer in about 2 years and i dont want to make a noob out of myself like i did with the mobo

any ideas?

thanks

I've built a lot of PCs over the years for myself and others and never had a bad (new) CPU. But I suppose it is possible. How'd you find so many 1150 MBs to test the CPU on?
I presume you had the CPU cooler fan plugged in at the time you tried the CPU.

I tried the cpu at a friend's computer shop and the cpu cooler was plugged in.


After doing looking up various forums and doing research, I find that I'm not the only one who has had a similar problem, where in a new build the computer won't boot up

If the breadboarding was done properly and the system would not boot to a POST screen, then I'd say RMA the CPU with an explanation.
 
Nope, a non-updated BIOS wouldn't even post as it won't even see that a CPU is there. Seen this many times.

Take the motherboard to a computer shop and ask them to flash the BIOS for you. It will cost money but it is about the only way to fix it, short of buying a compatible CPU.

Doesn't Asus have a thing to update the BIOS without a CPU in there.

It's about time they come up with an on board processor to handle that. Good idea. Now if they could just have it utter a simple, short message telling you it needs an update.
My old 775 board did. It said something to the like "processor not recognized".
