Newbie builder.

Parts:
Mobo: ASRock Z77 Pro4
CPU: i5-3570K; 4000BX80637I53570K
Heatsink: CoolerMaster TX3
Case: Fractal Design Arc Midi Black; FD-CA-ARC-BL
Power: Seasonic X750 Gold; SS-750KM3
Memory: G.Skill Sniper 4X (8GB) F3-1866C10D-16GSR
HD: Samsung SSD 830 Series 256GB; MZ-7PC256B/WW
Optical Drive: LG GH24NS90

1. Installed the memory, CPU, & heatsink,
2. Installed power supply and connected power cable to ATX Power Connector (ATXPWR1) and ATX 12V Power Connector (ATX12V1)
3. Connected SSD (connected to SATA port 0) and optical drive (connected to SATA port A1)
4. Connected the power switch cable (although not 100% sure that I got the orientation correct), the reset switch cable (although not 100% sure that I got the orientation correct), the P-LED cables, and the HD-LED cables to the System Panel Header.
5. Plugged in the monitor and hit the power switch...

Keyboard lights flash (just like they normally do), power button lights up, all the fans spin up, no beeps, no image on the monitor??

The power switch did not seem to turn off the system (and LED stayed lit) -- so I turned off the power supply). Found an internal speaker thingy (in with the case parts) and connected it to the Chassis Speaker Header. Have no idea if I have gotten the orientation correct (mobo is clearly labeled with one end as +5V, (middle pins are dummy), and the other end as "Speaker", but the actual speaker wires are both black and not labeled). Switched out the monitor, turned the power supply back on and hit the power button...

Same result. Keyboard lights flash (just like they normally do), power button lights up, all the fans spin up, no beeps, no image on the monitor??

Surely, I have missed a simple step that all experienced builders know to do automatically?? What is my next step in the diagnostic process?

Hi,
Sorry for being offline so long.

I'm affraid that I do not know what else you can try. It would be wise to check if speaker is working and to test memory and CPU somewhere (but it's a long shot) but other than that you may need to RMA mobo.

Hi,

Which GPU are you using?

Disconnect all LED cables from mobo. First row connectors (near to end of mobo) should be plugged in the way that name on connector should be pointed to near end of mobo, and the second row to memory and CPU so it could be readeble in when you look at them.

Now try to disconnect memory and try to boot without RAM to see if you're going to get any beeps and let us know.

Best regards :)

Thank you for the response.

Am not using a separate GPU (see http://www.intel.com/support/processors/sb/CS-031174.htm) . However, I did go ahead and install an MSI R6450-MD1GD3/LP Radeon HD 6450 as a simple test. Tried again and got the same result.

Forgive me but I am not sure I am understanding what you are suggesting about the LED cables. Can you re-state your suggestion (or show a picture of what you are trying to tell me)??

Hi,

Orientation for headers is next. First row headers must look oppossite direction from CPU, second row must look in direction of CPU.
have you tried disconnecting memory and boot your system to see if you are going to get any beeps?
For this time leave only SPEAKER and MB SW or PW SW depending on your case connected.

Best regards :)

0. Disconnected all the cables, removed all the RAM, and pulled the mobo out of the case. Set it on a non-static mat. And re-confirmed that the monitor was operating properly. Validated that there are no loose screws rolling around on the mob and no loose wires under the mobo.
1. Re-connected the power cable to ATX Power Connector (ATXPWR1) and ATX 12V Power Connector (ATX12V1).
2. Re-plugged the tiny system speaker into the speaker header. Technically, I do not know for sure that this speaker works as it is brand new (with the case), but there is not really any reason to question it at this point given the rest of the results.
3. Re-plugged the CPU fan cable back into the CPU Fan header.
4. Plugged the monitor cable back into the DVI port.
5. Did not reconnect ANY of the front panel cables.
6. Re-attached the optical drive to SATA3-0 (did not re-install the SSD into any SATA port).
7. Confirmed on the G.Skil site that my memory (G.Skill Sniper 4X (8GB) F3-1866C10D-16GSR) is supposed to work with this Z77 mobo. See http://www.gskill.com/en/configurator?manu=52&chip=41&model=767.
8. Inserted one stick of RAM into memory channel A1.
9. Turned on the power supply switch located on the back of the PSU
10. Shorted the PWRBTN pin to ground to start the system up...

Fan starts and I can hear the optical drive (with the board DVD) spin up. No beeps. Nothing on the monitor.

11. Switched optical drive cable out and tried the optical drive on all the different SATA ports. Same result. Nothing.

12. Tried a different stick of RAM and tried the RAM in each different channel. Same result. Nothing.

13. Removed all teh RAM and tried to re-start with no RAM whatsoever. Same result. Nothing.

I am not sure what else to try??
