Mt system has the following components (they are all compatible)

-Intel Core i7-4790K Haswell Quad-Core 4.0GHz LGA 1150

- ASUS MAXIMUS VII HERO LGA 1150 Intel Mobo

-EVGA Geforce GTX 1070 8GB GDDR5

--G.SKILL Trident X Series 16GB (2 x 8GB) 240-Pin DDR3 2400

-2x SanDisk Ultra II SDSSDHII-240G-G25 2.5" 240GB SATA Revision 3.0 (6 Gb/s) Internal Solid State Drive (SSD)

-Thermaltake 850W gold power supply

-Windows 10

-Aigo Atlantis Mid-Tower Chassis


I have had most of these components for years, apart from the gpu which I upgraded to 1.5 years ago. I recently bought a corsair ml240r rgb watercooler for my cpu and a new case. I rebuilt the PC in the new case with the new cooler and am now having this no post issue with the following symptoms.

When I try to turn the pc on:

no display

power button turns on the lights and chassis fans, but not off

fans plugged into mobo dont light up or spin (but fans and lights powered directly by power supply do light up and spin)

gpu and cpu fans dont spin, but gpu lights up

gpu fans twitch

motherboard lights up

no beeps or codes

I have checked all connections reseated ram and gpu. I have gone through all the no boot lists on this site.

My standoffs are all fine.

cpu should be seated fine because I never removed it.

psu should work because other things not connected to mobo work, also short tested it and it works additionally psu fan works.

Everything is connected correctly.

All of the components should work unless I physically broke them myself without noticing...

I have been frustrated trying to fix this all day and any and all help will be greatly appreciated. Thank you very much in advanced.
