Strange. So here is the setup:

Asrock Z87E itx mobo
Core i7 4790
12gb ram
600W Silverstone PSU
GTX 1070

So I connect it all outside of the case since case is coming in still.

Connected everything.

Turn on, nothing. Spins up, but no beep, no nothing.

Try different PSU

Same thing.

Tried different Ram

Same thing.

Tried without GPU and use onboard.

Same thing.

Tried with no ram to see if anything?

Same thing.


So do you guys suspect is the Mobo? If the CPU was bad, would it still not at least try to go to bios?

Got it used from Netherlands from Ebay (mobo). It looks brand new but they are apparently refurbished.

Could be the MB. If nothing spins on the fans then I'd say it's the MB. How do you have the MB set up on? Best be on wooden floor or the MB box or just a box. Carpet is a no no

of course not on carpet.

It was on the desk, which is wood.

Fans spin. Just no beeps or anything.

1. EPS cable plugged in next to CPU ? See Manual, Item No. 2 page 11

2. RAM installed in correct slots * ... as depicted in manual ? That would be 2 x 4GB ..or 2 x 8GB ..... not 3 x 4Gb (see edit)* or 8GB + 4 GB.

* EDIT:

Link for Manual .... http://asrock.pc.cdn.bitgravity.com/Manual/Z87E-ITX.pdf

Glad I checked ... you only have two slots ... see page 22

3. I don't expect that a board in this price range has troubleshooting LEDs but if so, determine the significance of status.

4. Cleared CMOS ? See Item No. 14 , page 11

5. CPU HS Fan connected to CPU Header ?

I used ram that is working and tested. I tried it with 1 stick in either slot. Nothing.

FYI its an itx mobo, it has only 2 rams slots.

You could try getting a new, soft toothbrush and some cleaning alcohol (believe it is called isopropahol alcohol) and clean the motherboard. That generally works with old mobos that I have. It cleans dust and thermal paste that could have gotten in the mobo.

Check bios jumper, replace battery, if the same get your money back

There is no bios jumper cap. Looking at the info online, it is used to clear cmos if you put jumper on.

@eidairaman1, I don't know if it is contact cleaner, but it might work. I meant isopropyl alcohol, also electronics grade if it exists there or 90% or above pure.

motherboard is as clean as a babies bottom.

Contacted seller. He said it was tested with a core i3 cpu and it worked. He thinks its the bios.

Great. I don't have another CPU.

Can you tell the bios version on your mobo. Sad that I'm in Europe and don't have any 4th gen CPU's or I would try and send one.

You could just get a cheap cpu off ebay. Guess the bios needs to be updated in order to support the cpu you have.

No pins are bent. Already verified that.

So a bios could be causing this? I notice latest bios supports for 4790k but mine is a 4790 non K

I already spent $400 for cpu and mobo. God forbid I have to spend more just because of the bios.

God must really hate me right now. Cause I am pissed like you wouldn't imagine.

That is possible because iirc a k ans non k have different clocks

Do you know for fact the cpu is good still and being inswrted right?

it was apparently tested on fleebay by seller. It is in mint condition too.

I know how to insert a CPU as well, there is a little arrow on it. I verified it twice if I inserted it correctly.

Been building machines for last 15 years and never experienced this one before.

Never buying used components like this again unless I verified it is working before purchase.

Just because the cpu isn't a K version or not doesn't mean that it's a supported cpu listed prior to the bios version is installed already

Well, probably is the BIOS. It all points to it. If you can return the board, as many said here, you could probably search for one that supports your CPU. @eidairaman1 I honestly didn't know you could clean components with contact cleaner. Nice, thanks.

here is the kicker. Seller is in the Netherlands. I am here in Canada.

Best option is now to either spend $150 cad for a dell computer with a core i3 in it or just count my losses and sell the motherboard at discount, same with CPU. And possibly sell a kidney to make up the loss.

Can't you talk with anybody who owns a 4th gen rig, so that they can help you? Can you ask someone to lend you a early Haswell i3? Spending an extra 150 bucks and calling it quits it's a terrible idea.

well, no its either spend the $150 or calling it quits.

And no, nobody I know has a Haswell I3.

So I am hoping someone here would be nice enough to sell me one.

I wont be surprised if my wife divorces me at this point for spending too much :p
