Hello, first time builder here, so any and all feedback is greatly appreciated. After double and triple checking that all my parts were compatible, I placed my order, they all arrived, and I sat down to do my very first build.

All went well until I tried to turn the motherboard on for a test boot into the BIOS. No matter what I tried, the mobo would not draw any power from the power supply. Not a single light turned on, no noises, no fans spinning, nothing.

My components include:

Motherboard: Gigabyte GA-Z97-HD3 (LGA 1150 socket)
CPU: Intel i5-4590 (LGA 1150 socket)
RAM: Kingston HyperX FURY 8GB DDR3 (2x 4GB sticks)
PSU: Corsair CX500 (500 watt)

My process:

I placed the CPU in the socket and installed the stock fan (I also picked up an EVO 212 cooler fan but decided to test it with the stock fan first), and plugged in the CPU fan connection. I then placed the RAM in the slots (following the manual to ensure the optimal position). I then connected the 8-pin CPU and 24-pin motherboard connectors on the power supply. I plugged in the power supply, turned it on, and then used a screwdriver to short the pins on the lower right of the motherboard. Nothing happened.

I tried this a few times and then decided to take it apart and try placing everything again. Still nothing.

I then used the "paper clip test" to ensure the power supply was working. When connecting the pins with a paper clip (as shown in a video from Corsair), it turned on and the fan started spinning, which it never did when connected to the motherboard. I can now assume the problem is not with the PSU.

I then decided to put everything back again, and try the cooler fan rather than stock CPU fan. Obviously this was just desperation (and required cleaning then re-applying the thermal paste), and as expected, it made no difference. It took me two tries to correctly position the radiator, so it occurred to me that there is a small chance I somehow damaged the CPU while doing this, although I feel that is highly unlikely as I very carefully placed it in the socket and was careful while screwing in the mounting bracket to ensure even pressure was applied.

At this point, what is the best course of action? Should I assume the motherboard is dead? Could it be the RAM or the CPU?

Thank you very much for reading through this. This must seem incredibly basic, but this is my first build and I am a bit frustrated that I cannot identify the problem so that I can begin working on a solution. I sincerely appreciate any advice more experienced builders could provide.
 
Once I plugged everything into the case, it worked when I flipped the switch. I know no one replied before I figured this out, but thank you anyway to anyone who might have!

Could anyone point me toward how I could now mark this thread as solved?
 


Which switch you turned?
İ have same problem please help me
 
I have run into this identical problem with the GA-z97X-Gaming 7 Mb. I am using an Antec Neo 550W PSU that was used in my old system and I confirmed its still functional.

The system is acting like its not plugged in...no lights, do clicks, nothing. I verified my case switch works and tried the onboard power switch. The power supply is plugged in, switched to on. I would expect to get something...even an error code. I've removed everything but one strip of Corsair memory, CPU Intel i5-6500.

I suspect a non-compatibility with the power supply. Research continues.
 


im fixed :) my motherboard is a new. but not power come..
im changed cr2032 bios battery now working :) try you to

I did try that as well without success. I just got off the phone with Gigabyte help support, they were awesome! The tech had me insure that the only thing plugged in was the CPU fan, one stick of memory. Then unplug both 24pin and 8 pin power...power supply off (O). Plug in 24pin power connector, select power supply to on (I)...the power switch on the mother board should light up (this piece of info would be handy to include in the manual). Then she had me power supply off...plug win the 8 pin power connector...power supply on...walla, lighted power switch. plugged in a keyboard and monitor and pushed the lighted power switch on the MB...it booted into BIOS! Hooray!

I would have sworn I did these steps several times but you can't argue with success! Ramadan...thank you for posting your successful attempt, it was much appreciated!
 


now your problem finish_? sorry my english is not good :)
