Question Weird black-screen error with an Nvidia RTX 3070 ?

[Deleted member 2980851]

Hey,

I'm using Fedora, previously I had Debian installed. I have already noticed the following error with both (I have had the graphics card for about 3-4 years, the error has been occurring for 1 week),

When I start my PC, I usually get a black screen that won't go away. It doesn't even show that you can enter the bios or anything else. I have connected my HDMI cable with my NVIDIA 3070 directly to my screen. If I use another HDMI cable or Displayport, the screen also goes black. If I turn the PC off & on often it might work eventually. If I do not connect my HDMI cable directly to the graphics card but to the connectors further up (to the motherboard) then I get a picture but in poor resolution & wrong scaling.

I would like to solve the problem. What can I do? Where can I start debugging? I have no idea.

Thanks in advance

Thanks for your reply.

- 48GB ram (corsair)
- cpu: intel core i9-10850k CPU @ 3.60 Ghz
- motherboard: asus tuf gaming z490-plus
- nvidia rtx 3070

I want to add: I already did a reset of my uefi settings. i only enabled intel virtualization and vt-d.

What is the make and model of your power supply (PSU)?

 

[Deleted member 2980851]

Ah, sorry @rgd1101 that i didn't read your answer clearly for the first time & thanks for asking again @COLGeek

The invoice I received from the manufacturer of my PC says "GEH NT ATX 750W Netzteil / ASUS ROG Strix 750G". (Netzteil is German for power supply).

I realized that it doesn't always work when i plug my hdmi cable into my motherboard instead of the graphics card. i tried it often today and it seems that it was just luck the days before.

Hope this info helps!

If you remove the 3070 and only use the integrated GPU (connecting your display to one of the motherboard video ports, of course), does everything work properly?

 

[Deleted member 2980851]

Nope, doesn't seem to work then either.
Out of interest: What ideas would you have if this were the case?

I would be thinking of finding a way to update the motherboard bios, perhaps using the flash bios button on the rear panel if you have one.

Have you tried connecting to a different display? Intent is to isolate the issue.

 

[Deleted member 2980851]

Good idea, I updated my bios. Unfortunately, it' didn't help.

I have tried connecting to a different display with different hdmi cables, yes. It also didn't work.

To confirm, the behavior exists with both a dedicated GPU and an integrated GPU?

If you boot from a Live Linux distro, not your installed OS, does the problem go away?

 

[Deleted member 2980851]

Yes, i tried it with both, the behavior still exists.

No, it doesn't go away with a live distro. I can't even get into the bios, because just nothing happens (unless after a few tries).

 

[COLGeek]

Then you have pretty much confirmed a hardware problem. The motherboard is the most likely culprit at this point.

You have a good PSU, do you know how old it is?

Have you tried resetting the motherboard BIOS (manually)?

 

[Deleted member 2980851]

The PSU is also about 4 years old

I also tried this, yes.


I've made a new discovery:

I originally said that a second screen does not work. This was because I started the PC and then plugged in the other screen while the PC was still running.
However, if I plug in the second screen when the PC is still off and then switch the PC on, it works perfectly. If I then plug in the other screen again, I have a picture again, but with the resolution of the old, other screen.


I still have no idea what the problem is.

You should NEVER connect/disconnect devices while your PC is powered on. You are very likely to suffer a catastrophic failure doing so.

Wait what? I am talking of my monitors? So i am just changing hdmi cables ^^

Never while powered on. You can easily short your system. When that happens, stuff dies. Those connections carry live power.
