New PC build with Asus Z87-PRO Q-Code 00

[zarophase]

Hi everybody,

Yesterday I decided to build my first PC
Motherboard Asus Z87-PRO
CPU Intel i5 4670 LGA1150
Power Supply: SeaSonic XP860W
RAM: Kingston KVR16N11K2 (2x 8GB)
I don't have a graphic card installed, the board has 3 video output (VGA, DCI, HDMI)

Once every thing has been put together I went to turn the system on and it didn't turn on.
The system didn't POST and the monitor went on sleep mode

Here is what I tried to do and my observations:

• The PC doesn't go to POST
• CPU fan turns on - plugged into the 4 pin slot (yellow) at the top of the board next to the RAM
• Chassis fans don't turn on (plugged into the chassis-fan pins), they only have 3 pins but should turn on
• Removed all the RAM and no beep sound happened
• Moved the RAM to the other 2 slots
• Disconnected all peripherals (HDD etc) only left connected the motherboard power and CPU power
• Tried to update the BIOS but when inserting USB in the USB slot provided for the BIOS update, the red light on the USB drive flashes for 3 seconds and stops all activity, when pressing the BIOS_FLBK button nothing happens
• Power light is is on (red colour) on the motherboard - when powering up, the Q-code is 00 for not used (I read that it means the CPU doesn't talk to the motherboard)
• Checked the CPU connectors for any bent pin, they all all fine (as far as I can see)
• Motherboard Revision is 1.02
• Cannot get to the BIOS to check the BIOS revision
• I disconnected all the cables except for the motherboard and CPU power and still gives me the Q-Code 00

I have looked on Google all night and tried what people with a same issue have done to fix it, but it doesn't seem to apply to this case.
Have I missed something?
Is my motherboard faulty?
Is the CPU faulty?
Unfortunately I don't have the hardware to check if the CPU is working fine

I triple checked that all the connectors were properly connected from the power supply to the motherboard
Now I am running out of ideas, if somebody can shed some light on this it would be greatly appreciated

Thank you in advance

Then that might be an issue (raised bits not long/high enough). But hard to say.
If testing the board out of the case and keeping somehow the board vertically while starting it (without touching the board's components), does the CPU fan spin?

 

[zarophase]

mmmh quite hard to achieve as I don't really know where to put the board outside the box for it to be perfectly vertical without touching/damaging the underneath.
I'll buy another fan as the one I've got is the intel that was in the box with the CPU and from what I have read so far it is by far not the best anyway

OK, but I still think that it might be the case shorting the board.

In this case should i put washers between the case and the screws?

I changed the fan and everything works fine

Thank you for the follow-up. Glad you've solved it.
