Asus Z170 Pro Gaming won't boot, LEDs on

[Chris_b86]

Hey guys I'm building a whole new rig and it's been years since I built a PC. Components are:

Asus Z170 Pro Gaming motherboard
Intel Core i5 6600k CPU
Cooler Master RR-212E-16PK-R1 Hyper 212 Evo CPU fan
MSI GTX 970 GPU
Corsair CMK16GX4M2A2400C14R Vengeance LPX 16GB (2x8GB) DDR4 2400Mhz
Corsair CP-9020061-UK Builder Series CXM750W PSU

I have rigged everything up, and the motherboard is lit up indicating that is has power. However nothing happens when I try to power it on. Nothing at all. I even thought it might be a dodgy power switch connecter from the case, so I tried shorting the power switch headers with a paperclip, no luck.

Please help! I've spent all day building this thing and I really need it to work 🙁

Are you using the display ports on the graphic card or the motherboard's?
Do you have any red LED that is constantly on around the motherboard?

 

[Chris_b86]

I am using the display port on the motherboard, I have removed the graphics card for now.
There is a red LED that is constantly on, in the manual it says this is the Standby Power LED, and indicates that the system is "ON, in sleep mode, or in soft-off mode".

What about the leds near the model name?

 

[Chris_b86]

They are all lit up (5 LEDs). There's also a pulsing red light along the left hand edge (dimming and brightening slowly - indicates "flowing mode" according the the manual).

Try bread boarding with one stick of ram.

What exactly do you mean by bread boarding? I've tried booting it with one stick of ram and had no luck.

Take it out the case and test it . make sure the ram stoick is installed correctly and you have plug in the power connector securely.

Ok after a lot of tinkering I got the thing to boot up - using a different PSU. Slightly irritating considering that I just bought the CXM750W especially for this build. Are faulty PSUs common? I evidently need to return this one. Many thanks for your time!

Try using one RAM stick at a time. There's a possibly that your RAM may be defective, causing it not to BOOT. I just checked your RAM, and unfortunately your RAM is not on the QVL list. Perhaps try RAM that is on the list? Let us know how this goes.

Chris_b86...... you ever solve your problem? I had this EXACT issue. The "best solution" got me to thinking. Your build was very similar to mine. I unhook ALL perfs and even the fans, and never got a boot. Swapped PSU and mem kit with a working build... no boot. Oddly enough, my issue was the EVO 212. The stand offs dug into the mobo membrane and ran a short on my mem kit. Pulled the cooler and it booted. So, I added some electrical tape under the stand offs and back in business. Hope this comment helped some one out there.
