Rgb and Fans Turn on but No Display

flotz

Hi folks,

First off, apologies if I am bill in the wrong are.

Got a doozy for y'all.
Long story short, I transplanted my HTPC from one case, to a slightly larger one to correspond a big GPU. Only thing I varied was the GPU.
Now, when I turn on the PC, AIO fans spin, GPU fans spin, Motherboard + GPU RGB turns on but there is no display unsuccessful signal. Tried the HDMI on the GPU, equally asymptomatic as the motherboard. Nothing. Just to be safe, I chucked in the older GPU into the new case and the problem persists so it cannot be the new GPU.

Eyeglasses:
Ryzen 3600 paired with EKWB 240 AIO
Asus X570-I Motherboard
Original GPU was 3070FE in the old example, ghost S1. Now Asus RTX 3080 TUF has replaced it. 3080 did non fit into the S1, sol I got a SSUPD Meshlicious. (sweet case, btw)
Corsair Vengeance RAM
Corsair SF750 PSU

Where did I f*ck upfield?

Edit: turns out it was a bad GPU riser cable that came with the case. I guess they involve to up their QC testing.

Thank you to everyone who took the time to reply with suggestions & troubleshooting ideas.

check your motherboard stand offs and make trusty there isn't an extra peerless shorting the motherboard.
also, quiz the scheme out of the case besides.

I'd definitely try it outside of the case to see if it will boot. Sometimes there's a short you just preceptor't notice and removing the board and replacing it in the case clears it finished.

Do I understand correctly that your system of rules starts normally just thither is no more output on the display? In any case, if your Mainframe has an iGPU then you can effort without the GPU installed and off the mobo display connectors.

What could have gone inopportune:
Maybe you didn't connect ATX12V or PCIe power connector.
Maybe the late casing allows argentiferous standoffs where your mobo has no hole, but you installed the repulsion, causing a short.
Maybe a metal know became informal and got lodged behind the mobo, causing a short.
Perhaps you tried to blood out the GPU from your old character without properly unlocking the retention clip from the PCIe slot, causing damage to the mobo or GPU.

Since it's a HTPC, I assume it's a non-overclocking CPU/Bachelor of Medicine that utilizes an iGPU/APU. The simplest come out may prospective be the Motherboard BIOS is set to display the iGPU/APU. Connect the HDMI to the motherboard, but WITHOUT the graphics card installed. Try looking in the BIOS and set it to display a sacred graphics card. Save and exit, deform off the reckoner, and so install the graphics card and connect the HDMI to it. Imag if that works. Also, sometimes the CPU/Megabyte iGPU/APU doesn't the likes of HDMI (specially on older platforms), you mightiness want to strain victimisation a VGA cable. Maybe it's your HDMI cable (least likely scenario)? Also... your ride herd on input might not atomic number 4 selected for HDMI input, but something else? It's difficult to troubleshoot with limited information.

I updated the OP to include a parts list.

Took everything unconnected, connected the PSU to the motherboard and powered it up, same problem. Doesn't boot. None signal from MB HDMI.

HDMI is plugged into a TV.

Edit: decided to hear to throw the 3080 in the artificial build, and boom. Shodden. With display.

Like a sho going to put everything back in the lawsuit and try again.

Took everything apart, connected the PSU to the motherboard and powered IT up, synoptical problem. Doesn't bang. No signalise from MB HDMI.

Edit: decided to try to throw the 3080 in the cardboard build, and thunder. Shoed. With expose.

Now going to put everything back in the grammatical case and try again.

The 3600 does not have a igpu. So that's not going to work. You need to be examination the telecasting card display entirely. Sounds like you may have had a ground job or a connector not sitting wholly

flotz

The 3600 does not take up a igpu. Then that's not going to work.

Ha ha. Overlarge mentality moment rightmost there. Irrespective, I still don't know why I was having trouble the premiere time some when everything was in the case.

So, put everything back in the lawsuit, powered it on.... Nope, back to the similar thing. Slay the business leader button, fans turn on, RGB on Megabyte+GPU, but no display out. you stumble the superpowe button again, it shuts downhearted immediately.

VGA LED is on the Megabyte, white LED per the hand-operated is the VGA error.

Ha ha. Plumping brain moment right there. Regardless, I still don't know why I was having trouble the first meter around when everything was in the case.
So, put everything back in the case, powered IT on.... Nope, back to the same matter. Hit the mogul button, fans turn on, RGB on Megabyte+GPU, but no display out. you hit the power button again, it shuts down immediately.

VGA LED is happening the MB, good LED per the manual is the VGA error.

see if it does that when you just short the pins rather than use the button.

flotz

I'm source to think IT's the riser cable.

visualize if it does that when you just short the pins rather than use the button.

Let Maine give that a go.

flotz

Sami thing when shorting the powerfulness clitoris pins. LEDs light-colored up and cycle colors for a few seconds and then jelled white LED.

In the meantime, I ordered just about 120mm Fan guards to hold up the PSU cables away from spinning fan blades

just to Be clear, you got it working extracurricular the case but now that its back in its not running again?
twice check the pcie cables, all cables really, make sure there are no insecure or bent pins.

just to make up vivid, you got it working outside the case but now that its back in its not working again?
countercheck the pcie cables, entirely cables really, make a point at that place are no loose Oregon bent pins.

Yes, that's what is making me consider that the riser cable is faulty. This is what it looked like outside the guinea pig, and it booted fine.

Will triple check again in the morning. I besides have the PCIE Gen 4 variant of the case that I was not wanting to use since this is scarce the HTPC but I power have that in to see if information technology really is the PCIE Riser main or not.

Zepher

I never proverb you mention a riser cable, that is plausibly the issue if the system deeds outside the case without it and doesn't work in the case with it.
you can forever test the riser forbidden of the case equally well send away't you?

ChosenUno

No melodic theme why you wouldn't test the riser cable outside the grammatical case, should've been an instant trial case every bit soon as display industrial plant.

flotz

Took everything apart, and tested it outside the case without the riser cable television and then with. Booted without, unsuccessful with. Swingeing riser pipe cable, regretful!

Grabbed the PCIe Gen4 Riser pipe from the other case and it works like a charm.

Rgb and Fans Turn on but No Display

Transplanted PC + changed GPU, now no Display unsuccessful. Incompetent GPU Riser
