Windows 7: Can't get new 6600K build to POST; AsRock motherboard

Can't get new 6600K build to POST; AsRock motherboard

In the last couple of days, I've been trying to assemble a new build with these new parts:

AsRock Z170M Extreme 4 micro ATX motherboard
Intel 6600K processor
Two 4 GB sticks of HyperX DDR4 2666 RAM 1.2 volt; matched pair sold as a single package.

All other parts carried over from working i5-2500 and all of these parts were working fine as recently as Friday.

No video card. I'm using integrated CPU graphics only.

I have no previous experience with AsRock or UEFI motherboards or Skylake processors.

Monitor connected by DVI-D. My monitor does NOT have an HDMI connector.

When powered up, I get nothing on the display at all. Nothing. Fans spin, drives spin, DVD burner drawer will open. Case speaker gives NO beeps whatsoever.

Manual says to hit delete or F2 to enter UEFI, but my mice and keyboards have no effect at all. Nothing on screen.

I've connected them to all possible combinations of all 8 USB ports: 4 USB 3.0 on the rear, 2 USB 3.0 on the front, and 2 USB 2.0 on the front. Shouldn't I get some screen output even with NO mouse and keyboard?

I've tried all the troubleshooting steps I can think of, including:

Clearing CMOS
Using 2 different mice and keyboards
One stick of RAM tried in all 4 slots.
The other stick of RAM tried in all 4 slots.
Both sticks of RAM tried in the recommended slots as well as other slots.
Disconnected all drives.

I even removed the board from the case and tried again with it sitting on cardboard with just the power switch, power cable, ATX 12 volt, and CPU fan connected. Same response: CPU fan spins, no beeps, and no on-screen response whatsoever.

I'm nowhere near attempting to install an OS.

I have no idea what BIOS I am on and obviously have no way of flashing or any reason to think that would help.

Please give me your best suggestions and let me know what should be expected on-screen IF hardware is NOT defective.

Most new/newer motherboards require two power connections. The 24 pin and either a 4 pin or 8 pin power connection. Do you have both power connections?

BTW, I'm using an older ASRock Z77 motherboard (with UEFI). Works great.

Hey Jack:

Would you expect screen output of some type when the monitor is connected to DVI-D only, with no user intervention???

No drives. No keyboard. No mouse. I'd assume I should see SOMETHING on screen, but I get nothing.

I've got all these parts out of the case right now, sitting on cardboard.

I'm aware of the 12 volt ATX connector.

My PSU has that ATX 12 volt cable connector split into 2 parts of 4 pins each. The 2 parts CANNOT be joined together into a single unit and then inserted into the board. Each is inserted as a separate unit, one after the other or simultaneously, but they are NOT connected to each other.

I used just one of the 2 halves (4 pins) and inserted it into the right half of the motherboard 8 pin header. It locks right in with the attached clip, as expected.

That worked well on my Sandy Bridge i5-2500.

Asrock support says that's also fine for a Skylake 6600K if you don't have severe wattage requirements such as high overclocking or multiple video cards. Asrock says no problem, because the right half of the header includes pins 1 and 5, which ARE required. I am connecting to pins 1, 2, 5 and 6, according to the user guide pin out diagram.

I don't use video cards at all. This system can't draw 200 watts at gunpoint. Maybe not even 150.

Nothing in the slots other than RAM. No cards.

4 hard drives. Mouse, keyboard, 23 inch monitor. That's it.

So why don't I use ALL 8 pins of the ATX connector?

Well----it's complex.

Those things are keyed as you know and will only fit one way.

Each half has a separate locking mechanism that slips down over a ledge on the back side of the motherboard header to lock it in place.

The right half that I'm using fits as expected, with the locking clip facing toward the top of the case, and the clip locks into the ledge on the back side of the motherboard port.

However--------------the other half of the cable connector is a problem.

Using reasonable force, it will not slide down into the left half of the motherboard 8 pin.

I wondered why and got out my magnifying glass and examined both the motherboard header and the cable connectors that fit into it.

Under magnification, some of the 4 pins on the left half connector are square and some have a rounded arcing edge. This is expected and what makes it a keyway when trying to put it into the motherboard. We're talking thirtyseconds of an inch here.

As near as my magnified eyesight will tell me, the left hand clip has been wired incorrectly by the PSU manufacturer. It won't fit into the board header with the expected orientation (locking clip facing to the top of the case, just like the right half) because it was wired 90 degrees out of rotation, incorrectly. The keyway does not line up if you have the locking clip facing the top of the case just as on the right half of the cable.

It WILL fit if you rotate the plug so that the locking clip faces left, toward 9 o'clock, rather than straight up 12.

However, I'm spooked of trying this for 3 reasons:

1: it's non-standard. I've never seen a 2 part locking mechanism arrangement in which each half had a different locking clip orientation.
2: there is no locking ledge along the 9 o'clock edge of the motherboard header, indicating that's not correct.
3: When in place, the right hand half locks in correctly and shows 2 yellow wires along the top, closest to you. The bottom 2 wires are black. If the left hand part of the cable is inserted the only way it will fit, locking clip facing left, you end up with black and yellow wires at the top, rather than yellow and yellow like the right hand half.

I could:

1: Assume Asrock support is accurate and that I only need 4 pins of the 8 pin ATX, regardless.

2: Assume my eyes are deceiving me and get out a bigger hammer and try to force the left half of the cable

3: Install the left half of the cable the only way it will fit, with the locking clip facing left, even though there is no ledge on that side to form a lock.

4: Listen to some people who insist 8 pins are required, despite what Asrock says.

5: Get another PSU out of the closet and see if that changes anything, presumably using all 8 pins of the ATX 12 volt connector.

6: Assume I've got a board problem and RMA for?


Or?

How do I eliminate the possibility of a bad CPU with no testing tools? It's rare, but happens.

Sorry for long post, but I had to give details on the ATX 12 volt thing.

The 8 pin power connector on my motherboard is keyed for the connector(s). The connectors from my power supply are also split in two 4 pin parts. My ATX power jack sounds exactly like yours (the manual says use the right portion on some applications).

Since you are not using a separate video card, possibly both halves of the power connector must be connected?

Other than that, you are faced with either a defective motherboard or CPU. I don't know how you can determine which is bad.

Asrock forum says no and that only 4 pins are needed for a standard setup.

But I will assume they are wrong and try my other PSU, hoping that it's keyed correctly and all 8 pins will go right in.

I don't expect that to make any difference.

I'm also going to remove the Noctua cooler and reseat the CPU.

If all was well, would you expect some onscreen text immediately after startup, just like on every other PC I've used, without using a keyboard at all?

I know nothing about UEFI, but expected something on screen and then hit F2 or Delete key to bring up some type of menu.

I borrowed a case speaker from another case. It gives NO beeps at ANY time, regardless of any variations I've made in configuration. I'm guessing the speaker is not defective.

Possibly Tommie can verify the plug you're questioning
Is this the psu in your spec's ?

Yeah, that's my PSU.

From my first post in this thread:

"When powered up, I get nothing on the display at all. Nothing. Fans spin, drives spin, DVD burner drawer will open. Case speaker gives NO beeps whatsoever.

The monitor if not connected and on you get at the very least No DVI-D cable image floating around around the screen

If not even getting that

Stab in the dark, but I`ve always found that nothing on the monitor means the cpu is not supported (wild stab there) or something to that affect. I`m sure it is, but start there.

It`s always best to lay new equipment out on a table and get it up and running before even considering putting it in the box, my Z170 sat on the table for a month before I even thought of the mega task of the rip out and reinstall into the case.

Another Skylake Journey !!

Troubleshoot it one step at a time Ignatz and I`m confident you`ll get it.

If not, return the board.

Oh, and I would definitely use the 8 pin power connector, regardless of what Asrock told you. The specs list it, so I would use it.
