Question Why is my computer no booting after a cpu upgrade?

[Extreme noob 45782]

I just upgraded from a i5 4670k to a i7 4790k and now my computer won't boot. The fan spin but no beep only a 00 code on the board.

I updated my bios to the latest one.Didnt solve the issue

I tried reseating the CPU, no luck there.

I tried the cpu on another Mobo it worked, the cpu is working.

I tried loosening the cooler no luck there either.

I tested my psu. No problem.

Removed the cmos battery to reset bios.Nothing changed.

I tried isolating faulty components no change and they all work with my old cpu.

Cpu i7 4790k no overclock
GPU rx580 4gb
Ram 2 x 8 gskill sniper 1866
Psu 1050 EVGA photon
Mobo Asus Maximus vi hero
Cooler Corsair h100i
Case cooler master box pro 5

Thank you for your help.

Check if you got the right 4+4 connector plugged in not the 6+2 PCI-E to power the CPU.

removed the GPU and any other external devices and power it on.

Edit:
also, make sure to disable XMP and any other OC setting to stock

The connector is the right one

And everything has been unplugged and still no boot.

Also it has no overclock on this cpu yet

Have you checked your BIOS version and if it needs updating to support the new cpu. I think the 4790k came as a later refresh so may need a newer BIOS version.

I did a new bios update to the latest one and still no change.

you need bios 1504 so check it and use the old cpu to update bios https://www.asus.com/ca-fr/Motherboards/MAXIMUS_VI_HERO/HelpDesk_CPU/

Have you tried only one ram stick also try changing SATA ports and cable? code 00 is very hard to pinpoint the issue.

I have tried switching the ram slot, only one ram stick and no ram stick no difference .

I also unplugged all hdds and no change there either.

If I put the old cpu it boots up normally,that's how I updated my bios.

try this; also use the latest bios

EDIT: doesn't require CPU or ram to be plug/inserted in
