Building a new system with a Z390 and Core i5 9500K. So far I have no post screen, no bios screen, no video / display out, no other indication of any kind. When I power up, I get a red 'breathing' (fade in / fade out) LED on the motherboard and after a few seconds, it will auto power cycle and repeat once or twice, then seems the MOBO stays on with the red breathing leds, but no video out / bios screen.
I've tried a long list of troubleshooting and come up empty. https://forums.tomshardware.com/threads/perform-these-steps-before-posting-about-post-boot-no-video-problems.1285536/ The only error I can 'force' is removing both sticks of ram which gives a 3-beep code (no / bad RAM?) With either stick in either slot the result is the same no post / no beep as listed above. The only possible thing I've come up with is my ram isn't specifically listed on the QVL list for this mobo - https://www.asrock.com/mb/Intel/Z390%20Phantom%20Gaming-ITXac/index.asp#Memory I have two sticks of Patriot Viper PVS416G386C8K (3866 MHz ram) https://assets.website-files.com/5cdb2ee0b102f96c3906500f5dd6b354f9822e94bd5132b0_PVS416G386C8K%20Sku%20Sheet_Copyable_062819.pdf Though both slower and faster ram are on the QVL. 3600 MHz https://assets.website-files.com/5cdb2ee0b102f96c3906500f5dd6b387f9822e3bd4513356_PVS416G360C7K%20Sku%20Sheet_Copyable%20062819.pdf 4000MHz https://assets.website-files.com/5cdb2ee0b102f96c3906500f/5dd6b33a8bbffce4aac8c12f_PVS416G400C9K%20Sku%20Sheet_Copyable_062819.pdf Is the RAM this critical that it HAS to specifically be listed on the QVL? Is there any way to force a 'fail safe' boot? Even if the ram is forced to a slightly slower freq setting? Thanks for any help you can offer!! Edited by ASRock_TSD - 31 Dec 2019 at 12:31pm |

Solved -
Looks like this was a combination of three factors: 1) The motherboard BIOS default appears to be 'no beep' on booting, so if the boot is successful you actually hear nothing - and without video, it seems nothing is happening. 2) The HDMI video port does not initially output any video - so my monitor hooked to HDMI shows 'NO SIGNAL' 3) My monitor hooked to the display port was initially looking for an analog signal, not digital and/or wasn't scanning fast enough to 'wake up' when the PC booted. Once I forced the monitor to digital input (it was working on display port with the old setup ?!?!), I was able to successfully catch the boot screen and start my OS install process. |

Nice. Exact same issue for me right now. Core I5-9600K w/ PVS416G360C7K memory as well. I think the monitor is doing the same thing. Looks for analog signal after it doesn't register a digital signal right off the bat.
I'll let you know how it come outs when I deal with the monitor. Thanks for posting your solution. |

Figured it out. RAM not seated. I'm always cautious seating RAM and I didn't do a good job of getting it in the slots. Seated the RAM right and everything is good. Well, except for the repurposed SSD I was trying to use. Should've bought a new one to begin with.
