dogg31 · Dec 5, 2015

Need help with a new build. The CPU fan turns on for less then a second and then stops. Here is what I am working with:

- Intel Core i7-4790K Devil's Canyon Quad Core 4.0 Ghz LGA 1150
- Gigabyte GA-H97M-D3H LGA 1150 Intel H97 HDMI SATA 6Gb/s USB 3.0 Mirco ATX Intel Motherboard
- G. SKILL Ripjaws X Series 16GB (2x8GB) 240-Pin DDR3 SDRAM DDR3 (PC3 12800) Desktop Memory Model F3-1600C9D-16GXM
- SeaSonic SSP-550RT 550W ATX12V v2.31, EPS12V v2.92 80Plus Gold Certified Active PFC Power Supply

Any help troubleshooting would be much appreciated!!

Did you install the little speaker that came with the motherboard it might give you a beep code telling you the issue...on another note... Why the unlocked processor and the board you can't overclock?

dogg31 · Dec 5, 2015

The motherboard did not come with a speaker. I'm new to building a PC. Do you suggest buying a better motherboard?

8-pin CPU and 24-pin motherboard cables connected?

dogg31 · Dec 5, 2015

yep.. both are connected.

I would return that board and buy a z97 board, or return the cpu and get a 4790(non k) or if you have a graphics card a 1241v3 xeon processor

Make sure ram is seated correctly, double check that. If nothing, try boot with one stick of ram only, trying each slot and stick

dogg31 · Dec 5, 2015

I tried each stick in each slot.. no joy

Here is a good guide to follow, there could be many reasons. Go through it step by step even if you think you have checked it already.

I'll go step by step and keep you posted.. thanks.

Still no luck... what are the chances I have damaged the motherboard in the process of all my troubleshooting? Again, new to this and just wondering how easy it is to do serious damage to the MB. Thanks.

If you were careful enough in the process of troubleshooting, it will be completely fine. But hey, it didn't work straight out the box anyway. So really it would seem you got a duff component on your hands. If you can verify this by means of using a different motherboard from a friend (or drop into a PC shop and explain your situation) this could shed some light on the matter. Another option would be to return the board as faulty, and as Supahos correctly said, get yourself a Z97 chipset unit seeing as you have a K series CPU.

Your boards BIOS need to be version F3 or later to support the i7 4790K, but that BIOS was released back in June 2014. As you have just newly received the board, it should have been manufactured with the lasted BIOS at that date. So there is a chance (and it happened to me) that it could just be in need of a BIOS update. I bought an MSI board and it had the same symptoms as you once, after a bit of investigating it turned out the "newly bought" board was almost 2 years old. Resulting in the BIOS being the very first version, -which didn't support newer processors. Have a look into this. The Serial number of the motherboard will often contain the manufacture date. After a quick google found this: http://forums.tweaktown.com/gigabyte/43875-about-manufactured-data-gigabytes-motherboard.html it might help you find the date.

Thanks so much, I'll take a look. Probably going to upgrade on the motherboard. Thanks for all the suggestions.
