Gigabyte RTX 3060 - No HDMI Signal

[PC_Noob_2022]

My specs:

Case: Phanteks Eclipse P500-A
MOBO: Gigabyte z690 Aorus Ultra
CPU: Intel i7-12700k
Gfx Card: Gigabyte GeForce RTX 3060 VISION OC 12GB
RAM: Corsair DOMINATOR Platinum DDR5 (5600Mhz) 2x16GB
HD: Seagate Firecude 2TB SSD M.2
PSU: Corsair RM850 850W 80+ Gold

Hi, firstly I should say this is a new build and has never been booted (succesfully) yet.

My current problem is that there is "No Signal" to my monitor via HDMI on the Gfx Card BUT it does recognise that the cable is in; just that there is no signal.

I also don't have power to my rear or front I/O and I don't know why.

I have checked my motherboards capability and it says it supports DDR5 RAM up to 4800 Mhz *but with XMP it should support the RAM I'm using. (I just can't enable XMP cos I can't boot. or at least can't see if it has because no signal)

Is the RAM causing a problem that stops HDMI signal and or the power to I/Os?

The other thing it could be is that somehow my Graphics card is not sending a signal? I will have to test my old card on this setup.

Thank you for any answers or information about this!

Self build or pre built pc ?

Have you tried the displayport ?

It is self build and I don't have at the moment DP capability so I am still using HDMI (sorry)

 

[PC_Noob_2022]

You are plugging it into the cards HDMI and not the motherboards HDMI ?

Yep, it is recognised too because when no cable is detected on this monitor it says "Check signal cable" but here it says "No signal" so the cable is recognised.
Also the monitor and HDMI cable work on a different system.

 

[PC_Noob_2022]

Are all the PSU cables definitely fully plugged in?

Everything is plugged in correctly it is in my belief a component acting up.

Check all power cables and reseat the gpu, check the motherboard for any bent pins. Also try one stick of memory

I have done all this but is it a solution to use my old graphics card to see if it boots then? As I haven't tried that.

 

[PC_Noob_2022]

Okay I tried the old GPU (which definitely works in another system) and it also received no signal.

Also I am getting a "C1" error on the Mobo LED, is this a problem that can prevent a boot?

Spoiler: MOBO Error

Here also is what the Gfx card looks like etc when I turn it on

And finally here is the difference between No HDMI plugged in and HDMI plugged in on the monitor.

Spoiler: No HDMI

Spoiler: HDMI Plugged In

Is any of this clear as to a particular problem? I am stuck thinking whether it must be the Motherboard itself or the CPU? *UNLESS C1 error does prevent a boot.

 

[PC_Noob_2022]

Reset the BIOS first.

Is it possible to reset the BIOS without being able to boot or getting power to any I/O?

Have you tried the GPU in another machine.

I don't have another machine that can fit this card atm

 

[PC_Noob_2022]

Have you got your RAM in slots A2 + B2?

Yeah I have them in those slots

I will try follow this;

You can clear the bios by disconnecting all power, remove bios battery and set the clear cmos jumper on the motherboard. Leave for 10 mins and reset jumper, etc then try to boot.

 

[PC_Noob_2022]

There is a BIOS reset jumper on the bottom right side of the board above the front panel connector and below the battery, this is the best way to do it.

Remove the battery as was said first too?

 

[PC_Noob_2022]

IF you use the jumper you don't need to remove the battery no.

Okay I tried this twice and I still get the same "No Signal" on the Monitor. There are no beeps from the motherboard or anything.
As far as using a USB stick for QFlash my motherboard is not receiving power to those ports so I don't think it would be possible?

Is there a particular piece of hardware (Maybe the motherboard itself?) that is causing all my issues that it would just be easier to replace?

I bought everything on Amazon btw.

 

[PC_Noob_2022]

Is that just the 'boot' LED lit up in the picture or one of the other ones?

Yeah it is the boot LED indicator.

Does the CPU fan spin up when you try to power the system up?

Yeah all fans are running, the GPU fans shut down after a second which is apparently normal until they reach appropriate temp.

just the CPU, GPU and RAM, literally nothing else.

Apart from the M.2 SSD and PSU that is all I'm using anyway, would this be to test something particular?

 

[PC_Noob_2022]

Okay I tried unplugging all extra stuff then rebooting to see if that was the problem.
Here is a picture to show what I had plugged in and what I tested removing. (It is possible you know better than me that I don't have something in that I should have)

Spoiler: MOBO Manual 1

Also upon reading the MOBO Manual further I found this page and this particular light is on. Is this a clear indication that my RAM is faulty?

Spoiler: MOBO Manual 2

 

[PC_Noob_2022]

You sure you are pushing the ram down until it clicks in?

Unfortunately yes.. I have tried both sticks individually in each position and I get the D-RAM LED in all attempts.

 

[PC_Noob_2022]

All you need is the motherboard, psu and usb drive with latest bios.

Can I connect the new motherboard to my old system to access USB that way as it is unpowered I/O on this system?

 

[PC_Noob_2022]

Insert the usb drive in the correct flash port and press the fkaah button

I will try this tomorrow morning thank you.

Supposing it doesn't work what is the remaining fault? Having to replace motherboard?

Given the D-RAM LED fault showing, is there any possibility that replacing the RAM could be the only problem? AFAIK that shouldn't prevent boot or deny power to the I/Os?

 

[PC_Noob_2022]

Let's us know how you get on.

Okay I QFlashed the BIOS and still have all the same problems including C1 error so I will try get my hands on some alternative DDR5 RAM to swap in and see if there's any luck there.

 

[PC_Noob_2022]

I'm guessing you tried each stick individually in every slot ?

Did you have a closer look at the cpu motherboard socket for bent pins while it was out of the case.

Yeah tried every slot and I couldn't see anything wrong with the socket unfortunately, at this moment I am hoping it is the RAM cos it's easy to fix lol

 

[PC_Noob_2022]

Have you taken the CPU out and inspected the socket yet?

Yeah, it's intel so at least as far as I can tell there's nothing obviously wrong.
As a small update I have also tried now Display Port and get no signal on that either through my new card, on-board graphics or my friends (confirmed working) card.
I think I will take the RAM to a PC shop to have it tested and if it is okay I will then replace the motherboard, what do you think?

 

[PC_Noob_2022]

Replacing the Motherboard solved the issue, so it must have been faulty! Thanks everyone for replies!
