Hi, my friend attempted a build very similar to mine in that we're using the
Intel Pentium G3258 w/ ASROCK Z87 Extreme3.
He has told me that he is able to press the power button and have all the fans from the PSU/CPU/GPU spinning. And that it is also attempting to find a boot prompt in that it will spin, stop spinning and start again, indicating to me that it is attempting to POST and boot but unable to since their is no input.
I think that it is a problem with the I/O Panel.
We have gone through the checklist and still have no power output from the I/O panel. He tried plugging in a USB keyboard which is suppose to light up but then didn't. He also tried to charge his iPhone but it also received no power. In a twist of fate, he is actually using 6 Motherboard standoffs when there is actually space on the Extreme3 for 7, which I have and mine works. Do you all think it is the standoffs or that the motherboard is broken in some way?

The fan stopping and restarting (and, I assume, then spinning normally thereafter) might be a natural feature of how the Motherboard begins the boot process.

Have you tried a different monitor and/or DVI cable? It's possible that's at fault.

You could also try attaching a Graphics Card and connecting the Monitor to that in order to see if the Motherboard's DVI Port is indeed at fault. Even without drivers installed the Graphics Card should still output an image sufficient for BIOS access, Operating System installation and low-resolution display.

You can hear the Motherboard's POST beep-codes if you install a Motherboard Speaker to what I believe the Z87's manual refers to as the 'Chassis Speaker...

When you say 'went through all the checklist' could you specify what you did?

Ensure the Motherboard standoffs are equipped with rubber washers to prevent the case potentially shorting the Motherboard.

Ensure the 24-Pin ATX Power Connector is firmly attached and the 8-Pin CPU Power Connector. Have you used the correct cable for every connection type and is it securely and firmly attached? Just read a thread where someone's ASrock Z87 Extreme 3 would switch off after roughly 2 seconds and it was due to him using the wrong cable somewhere.

Make absolutely certain that your CPU Cooling Unit is firmly and securely attached as a loose cooler will result in an overheating CPU causing the system to power down.

Be absolutely certain ALL fans inside the case are spinning, especially the CPU Cooler.

Try resetting your CMOS and booting your system with only 1 Stick of RAM in the manual's specified primary slot.

In order for a PC to POST you simply need a Motherboard, CPU, CPU Cooler, PSU and 1 stick of RAM. If your Motherboard doesn't feature Integrate Graphics then you'll also need a GPU to see an image. The I/O Panel has nothing to do with any of those components except, potentially, an Integrated Graphics unit. Your I/O Panel is unlikely to be the cause. We're forced to assume all components are working until we've tried all other options.

Let me know if any of those steps produce results.

Hello, he recently breadboarded the entire build and took out the MOBO, CPU/Heatsink, and RAM and put it on the box to boot up. Once again, the Heatsink spins for a little bit, stops and restarts and then continues to run yet there is no display from a DVI cable connected to the motherboard. He is only using one stick of 4GB 2133 G. Skillz RAM (which might be a problem because it runs at a higher voltage than recommended).

You can hear the Motherboard's POST beep-codes if you install a Motherboard Speaker to what I believe the Z87's manual refers to as the 'Chassis Speaker Connector' (indicated by the number 18 on page 11 of the manual) where you can see a diagram of your Motherboard's layout). These are cheap and also should be easily borrowed from any location that deals with computer hardware. This will give you quite an exact idea of the specific problem if none of the above proves helpful.
