ASUS motherboard intel chip no boot no bios

Specs: Windows 7 Pro OEM
I have just assembled my own machine, everything powers up, but there is no boot on the monitor, I put the OS install disc in the DVD drive, which spins but still nothing is showing on the screen. I have put together many machines before. Everything appears to be connected correctly.

Please post your complete spec list. Did you bench test the hardware before installing it in the case? If not, strip down your build & start over.

I built the same machine twice with the following hardware, and the same issue occurred on both builds...all parts were brand new. I did not bench test, but maybe I'm missing some compatibility issue. Should I attempt to boot without RAM?

I have attempted to boot to BIOS with the PCIe GPU card, and with the onboard VGA

Intel i5 CPU
ASUS ATX DDR3 2600 LGA 1150 Z97-K/CSM Mobo
Cooler Master N400 Case
Corsair Vengeance Blue 8 GB PC3-12800 1600mHz DDR3
Corsair CX Series 750 Watt ATX/EPS
LG Electronics Optical DVD Drive GH24NSB0B
Crucial MX100 256GB SATA SSD
MSI AMD Radeon R9 270X Gaming 2GB GDDR5

"Should I attempt to boot without RAM?"

A system won't boot without RAM installed, but if the board has a built-in speaker or you have the case speaker connected, it should beep like mad. If it doesn't, there are several possibilities - board is bad, CPU is bad or improperly installed, 4-pin/8-pin ATX12V plug isn't connected, board is installed improperly & shorting out, etc. That's why the bench test step is so important. The idea is to rule out problems before final assembly.

You should have placed the board on a non-conductive surface, installed the CPU & heatsink, one stick of RAM, connected a monitor to one of the onboard video ports, the power supply, & a keyboard. A case speaker & power button would be helpful if the board doesn't have them built-in, but the board can be jump started using a flat blade screw driver. Nothing else is needed. If the system fires up & you're able to access the BIOS, you'll know the base components are good & assembled correctly.

I appreciate your answer, but it doesn't really answer anything.

ATX is connected - absolutely

Board is NOT shorting out - absolutely.

Both CPU are bad? Unlikely.

Both motherboard are bad? Unlikely.

Case speaker is connected, and not making any noise.

I'll pair back to one RAM stick and disconnect the SSD and DVD drive and see if that makes a difference.

"I appreciate your answer, but it doesn't really answer anything"

You didn't bench test so I'm suggesting that that's what you need to do. If you leave everything in the case with all the non-essentials connected (hard drive, optical drive, video card, extra RAM, mouse, etc), it will likely take you quite a while to sort things out, unless you get lucky. The fact that you're not getting any beeps is significant. Are you sure the CPU is supported by the board & the correct BIOS is installed? Sometimes a newer BIOS is needed for a newer CPU. There are a lot of different i5 didn't state which one you have. This board only supports 4th gen CPUs.

Sorry. It's Intel Core i5-4690K Processor 3.5 GHz LGA 1150.

According to Partpicker it should be supported...

How would I flash a new BIOS if I cannot get the board to power up? Can I do that in the bench testing?
