I already build couple PC's in my life and this is the first time I am seeing things like this... I was building a PC for a friend, every new part from the store was carefully selected and I have checked CPU compatibility list to see if the CPU is supported by this motherboard (Yes it is) and other stuff.

This PC has:

Gigabyte GA-H87-HD3 H87 s.1150
Intel Core i5-4690 3,5 GHz 6MB cache s. 1150 Box.
2 sticks of Kingston HyperX 4GB DDR3-1600 Non-ECC CL9 Black KHX16C9B1B/4.
Gigabyte GF GTX760 2048MB 256Bit PCI-E OC
Seagate ST2000DM001 2TB sATA III 64MB.
Chieftec A80 Series CTG-600-80P Bulk 600W.

and is put together in this case Zalman Z3 Black USB 3.0.

I have put everything correctly, made sure that every part is connected properly etc, I have tried to turn off the PC and here is how it does:

Power LED lights on and fans start spinning for 1 second (both case fans and CPU fans and GPU fans) -> then pc turns off itself -> then pc turns on itself for a second (again everything for a second maybe two spins) -> then everything turns off itself -> and it's in this endless loop for eternity.

There is no beep errors from system speaker, no warnings nothing.

I have proceeded then to slowly removing components to see if it boot:

First I have removed the GPU as there is the integrated one so it should boot = not working
Then I removed one ram stick, tried swapping ram sticks, tried different ram slots = not working
Then I've checked CPU, if there is a pin bend or something, everything seems fine = still not working
Then I've removed both ram sticks, and booted the pc = not working
Then I proceeded to removing cpu and turning it On... well it gives the same signals when I remove the cpu from the slot and turn it On (meaning it turns itself for a second, then turn itself off.
Then I proceeded to checking the PSU on different pc with core 2 duo on board, 2gb of ddr2 and geforce 9500, PC turned on properly and everything worked fine so the PSU might be Ok.
Then I checked if I put isolation pads on every screw on the motherboard, everything was there, I didn't miss one = still not working
I checked if there isn't any extra screws bellow the motherboard that could technically connect case with motherboard and made problems but the only screws I saw ware the ones where the holes In motherboard was and motherboard was connected via screws to them.

Right now I am out of ideas on what could be happening, I am thinking out of those categories that either:

- (might be 90% of chance that this might be the case but I don't have any means of confirming it) The cpu is supported by this motherboard, but there might be outdated bios on the motherboard and thats why it doesn't start because the older bios don't support this CPU and thats why it isn't starting

- (I think there might be 40% chance of this, but I have no means to confirm this - i don't own spare hardware so I would have to go to store where we bought the stuff) CPU or Motherboard is broken out of the box and needs replacing for a new working one.

Could someone please help me and explain what is going so very very wrong over here, what steps I could take to determine the cause and fix it etc. I am counting on you guys because this whole thing is starting to depress me... Please Help Me :(
 
You have a short .

Check the power switch and reset switch first , by disconnecting them and then starting the pc by touching the power switch pins on the mb with the tip of a screw driver momentarily

You may not be getting beeps because the mb has no speaker . Get one and plug it in

Actually right after this started to happen I have disconnected every pin from the case control panel (meaning Reset switch, hdd led, power led, I only left the speaker connected and Power button connected) and left only the power as it still was happening and this didn't helped then I have turned on the pc on the power button and while the PC was in the reboot loop I have disconnected the power button pin from the motherboard (so the case front panel was disconnected fully, even the power button) and it still was restarting even when no buttons was connected from the front of the case.
Should I still try turning On the pc with screwdriver or not?


I have connected the speaker, its there.

I think it's a little to late about that, also every thing should work out of the box, manufacturer should either write that this CPU will not work without bios update or they should keep bios up to date or find a way to update bios without a cpu >,<

anyway what can we do about this if it is outdated bios? Will they do something about this in the store? I don't have a spare CPU to put in and update the bios.

I don't have any means of contacting Gigabyte so I can only go to the store with the whole PC on Monday and see if they can flash it or send the motherboard for warranty so they can flash the bios up there. Thanks for your suggestion and if you have something more to add please do, I am very grateful for your help over here ^_^

In mean time I will be observing this topic and waiting for more suggestions/help/replies on this matter, all help is appreciated.

We went to the store where we bought the parts, they charged us 50 PLN to reflash bios to newer version. This Motherboard had F5 installed on board and thats why the CPU didn't boot. They have flashed F8 and everything works. BTW. It sucks that we had to pay to flash the bios...

Hi. I have the same board H87-HD3
Core i5 4430 Costa Rica processor

Samsung 1600 MHz Ram

My PC just running no video or beep.
After one hour it shut down. Then I have to start again manually.
I tried everything but no luck.
Is it needed bios upgrade or anything else?
Thanks in advance

You probably didn't put in in the case correctly because it shorts out from the metal case so take it to a guy and ask him for post screws, put them in first then screw your MB in, if you didnt take it out try looking for blown capacitors or check the current to make sure nothings blown

use spacers or post screws because its probably shorting out but if it doesn't work you fully shorted out the motherboard
