Hi All,

This is a new build. When I built it the first time, I installed all the components and when I turned it on, the PSU, Case and GPU fans powered on for a second and then shut off. There are no beeps from the motherboard. The green light on the power button on the mobo stays on. If i press it again then nothing at all happens. But if i shut off the power supply for 5 seconds till the light goes off and then resume power to the PSU and then press the on button on the mobo, I see the same fans spinning for a second and shutting off.

I proceeded to remove everything except the CPU, PSU and mobo and then I observed the exact same phenomenon. I tested the PSU using a PSU tester and it seemed to test ok. I then assumed that it was a mobo issue and I RMA'ed the mobo.

After getting the mobo back, I reassembled everything and I get the exact same problem. I am currently on the verge of RMAing my CPU as well. Reading other threads on this topic, most have suggested a mobo issue but Gigabyte claims to have repaired mine. I have been extra careful to be static free and everything.

My build is as follows:
Mobo: Gigabyte Z87-UD4H
CPU: Intel i5-4670k
RAM: Gskill Sniper 1866 MHz 16 GB DDR3 CL9 (9-10-9-28)
PSU: EVGA 750W NEX750G
GPU: Galaxy GTX780GC
HDD: Seagate Barracuda 1TB 7200 RPM
SSD: Samsung 840 EVO 250GB
Case: CM Storm Scout II

Apologies for the long post, tried to be detailed, help will be greatly appreciated.

Your going to have to upgrade your bios before if will work with your new CPU. I believe your board supports a system called Q-Flash (http://www.gigabyte.com/webpage/20/HowToReflashBIOS.html), but this still requires a CPU in the board!

You either have to borrow an old CPU to run the board and update the bios (?), exchange your CPU for an older model (?), or take it to a repair shop who will be able to flash it for you with an older CPU. Alternatively you could try returning it to the manufacturer and ask them to update the bios - but only if they have a local base. You don't want to send it back to Taiwan!

This seems to be a regular Catch22 which is catching people out at the moment. It's a drag, and something new builders really...

Hello,

I second the BIOS solution. I had a similar issue with my Sabertooth x79 board. Luckily, it has an EZ flash USB port on the I/O panel and I was able to flash the updated BIOS without powering the system on. It drove me mad for a while. I'd check and see if your processor has compatibility issues with the motherboard, and if Gigabyte has a listing of BIOS revisions on their site determining any compatibility issues. You may just have a peice of hardware the motherboard is saying 'no' to.

Also make darn sure the CPU is sat properly in the socket and you have a decent thermal contact with the heatsink. Simple things, but easy to overlook.

Hi Captdonno,

Thank you for your response. The motherboard is a Z87 motherboard and the i5-4670K is one of the most popular LGA 1150 processors and I haven't heard of any compatibility issues. I'm also a noob and have no idea how to flash a bios without entering the bios utility which would require the cpu. The gigabyte support website is not very helpful in this regard either.

Sorry - don't think I've been much help.
