[SOLVED] Newly built PC no video display

[jojamon]

Hi all,

First time poster here, need some help.
Putting together 4 workstations for office use, list is here

https://ca.pcpartpicker.com/user/jojamon/saved/#view=L3WTCJ

So I have 1 workstation running the Thermaltake H18 Versa case https://www.amazon.ca/gp/product/B079G3TNDM/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

The other 3 are housed in a Rosewill SRM-01 case

I've since put together one in the Rosewill SRM-01 case and it runs fine, I got Windows 10 installed and everything.
The other one I've built in the Thermaltake case, with the exact same interior parts, isn't running video. I tried the VGA and DVI outputs on different monitors that are WORKING, and I'm still having the same problem.
I went through the steps here

I have motherboard standoffs installed in the Thermaltake case for sure, I even took out my motherboard to check.
My PSU plugged in and turned on has the CPU and chassis fans spinning normally. No beeps from the chassis speaker.

I tried removing 1 stick of ram, still the same issue, no video.
I tried moving the ram sticks into different slots but still no video.
Removing both sticks of ram, so having no ram in the mobo, gives me 1 long beep and then 2 long beeps, but still no video.
Been struggling with this for over 1.5 hours now, and still no good.
Is there a possibility that the mobo is dead on arrival?

I'm just running integrated graphics from the i5-9400.

Thanks!

edit: I should note with the one I successfully booted up, I could go into BIOS before installing Win10, and I flashed the BIOS using the Asus EZ Flash so it supports the i5-9400.
With the Thermaltake case, I have no video output so I can't even get into BIOS.

Can you post a picture of the information atop the CPU's IHS? According to this support list, you should be good to go with BIOS version 1405 unless you have a latter revision for the CPU. Might you be able to recall what the BIOS version on the one system you got working, was?

So out of the 4 system's, only one works out of the box? Might want to breadboard all the boards and then work with bare minimum's.

Hi Lutfij,

Thanks for your response. It turned out to be a defective motherboard. Swapped it out with one of the working motherboards and video works fine.
