I just bought a gigabyte GA-Z87X-UD4H mb and a i7 4770k cpu.  I've installed the CPU, attached power, and 1 stick of 4 GB G-skill RAm.  I have a hdmi monitor plugged in.  Oh, yeah, I've also got a Hydro 50 water cooler on the CPU.  But when I press power the unit turns on for one second and shuts down...  No numbers, no clue.

Is it the board?  The CPU (not seated? or too much paste?)   What do I do to identify the problem....???

i suggest to use the minimum setup, as described here, for troubleshooting :

If you have thermal paste oozing out and dripping onto the surrounding circuit board, then yeah - there's too much.

If it's just squeezing out along the edge of the raised CPU chip but not reaching the lower surface, then it's not TOO much.

Check if the memory module and the heatsink are seated ok. Try to reseat them.

Have you installed all the power cables, the 4pin near the cpu and the one that leads to the graphics card?

Do you listen to any beep codes? Have you installed the speaker in the motherboard?

Are you using a high-quality power supply?     Some lower-end PSU's wont' work well with Haswell chips.

Also, did you connect both the 24-pin ATX power supply and the 8-pin auxiliary power connection?

Yea buddy, it sounds like its not getting enough juice. Either get a second powersupply, or one real powerful one

or try it without the cooling for a minute, see if that helps

no need for oversized power supply - just calculate what you need, and leave a 50 W margin

I was out sick, but I'm back.  I think the problem was the paste, it has oozed beneath the chip.  I had an old stick of Arctic 5 that apparently "separated."  When I added the heatsink the pressure made it runny.

I needed to be up and running, so I picked up a used 787x-ud3H.  New paste.  So I'm up and running.  I don't know how to clean out the goo inside the chip space... (is the board ruined?)

I gotta also ask.  The UD4H mb was significantly better made than the UD3H.  I feel "cheated" now.  LOL.   In your opinion(s) is it worth it to get another UD4H (if this one can't be fixed)?  I'd sell the UD3H.

You can clean it carefully with a cloth and a small dose of alcohol.

I would use a slash-cut nylon bristle paint brush and 99% isopropyl.99 percent Isopropyl Alcohol
