Posted: 30 Jun 2020 at 4:03am
Hi.
I just put together a build but it wont post. I know the ram is good, because I have another system built on a Z370 Pro4 that has been working great, and I swapped out the ram between the two systems. Both sets of RAM worked on the Z370 so I know they are good. so I know the RAM is fine.
All the fans are working. No beeps, just a steady pulse of the blue lights on the motherboard.
I know this board at one time worked fine because I installed it on the other system until I realized I needed a different PCI slot so I got the Z370 and used that. So the Z390 *should* work.
So, I read a bunch of email from this site and none of the proposed fixes seem to apply - I attached a 8-pin CPU cable to the ATX12V1 connector, a 24 pin cable to ATXPWR1. FWIW, I did not connect anything to the 4-pin ATX12V2 connector. Do I need to -I don't have another CPU cable.

When I supply power from the PSU the blue lights on the motherboard start to pulse maybe once per second.
When I press the power button on the IO panel all the fans (case fan, CPU heat sink fan, and GPU fans stat up. The only think I hear is the tiny amount of crinkling that IIRC is a hard drive starting up.
I get no output from my GPU. No beeps no sound, just the fans running and the steady pulse of blue lights.
I hear NO beeping at all. The IO panel connectors seem to work fine - I have IO panel lights and the power switch starts the CPI and GPU fans.
This is my build:
ASRock Z390 Extreme 4
Intel I9-9900KF (coffee lake) CPU - no onboard graphics.
Corsair Vengeance LPX DDR4 2x16GB (32GB) 3200 MHZ
Hyper 212 EVO heatsink/fan.
Gigabyte GEForce RTX 2060 Super Graphics card
Corsair RM850 power supply.
Fractal Designs Define R5 case.
Crucial MX500 SSD
Seagate Barracuda SATA Hard drive.
I really haven't seen any means of diagnosing the issue.
Thanks fr all suggestions/advice,
Fraser
