New 4080 not working. Unsure what the problem is :(

[Lazzios]

Hey guys, built a new rig a while back for the RTX3090 and after about a month the 3090 died. Not really sure what happened to it. 

 

Since then I've been surviving on a 1660 for about 18months and have had no problems. 

 

Plugged in  the new 4080 today, monitor can't detect a signal, and there is this red light on the graphics card. No Idea what it means. 

 

Any help would be appreciated. Thank you!

Is it's power cable fully clipped in, and firmly inserted?

 

What PSU do you have? And what motherboard model?

From what I can see it appears to be fully clipped in. It was easy with the adaptopr, wasn't too fiddly.
The PSU is Corsair HX850 850W High Performance Power Supply, 80 PLUS Platinum, 135mm Fan, Fully Modular
And the motheroard: Gigabyte Z490 AORUS PRO AX ATX

While you're at it, you might also want to clean out that radiator. It's a dusty boi.

It certainly wouldn't hurt, you aren't wrong haha.

I would recommend, while waiting to see if someone here knows, that you start your support request with Zotac. They may be able to answer faster.

What type of cable are you running from your GPU to your monitor?

 

It should be the easiest thing to diagnose right now, maybe the 40 series is iffy with the cables you plug in.

Tried both Display Port and HDMI. Neither get a signal.

What have you done before installing the new card?

 

Did you DDU the driver of that 1660? I find it strange that 2 GPU's didn't or stopped working in your build, especially with such a good PSU.

Can you list your full specs?

red light means;

 

no power

bad power

bad voltage

no calbe detected

First GPU was eVGA GeForce RTX3090 FTW3 Ultra 24GB (This one worked fine for about a month, and then stopped working after I played GTAV on the PC for the firs time. Screen went black after about 20 min. Rebooted PC, died after anohter 20min and then never worked again)

Have been using a MSI GTX 1660 for the last 18months with zero problems

New Graphics Card is a Zotac 4080 16GB Trinity

I did not DDU (Display Driver Uninstall?) I jsut turn off the PC, switched out the card, adn tried both display ort and HDMI, got no signal. I feel like that its something within the PC though.

Try the card in the second slot, assuming there is a second slot, just to see if it is a PCIe issue with the main slot.

I remember trying that with the 3090 and it not fixing anything. So I'm just a little hesitant switching PCIe slots incase reapeated attempts at turning it on damages the card if it is a power issue.

Just brainstorming here, try fliping the single/multi rail switch on your psu (I don't think it will help, but I am curious at this point)

I was literally just taking a look at that (pulled the PSU out to check th ecables were secure which they are)

The red shows where I have the 3 8-pins plugged in and it is set to "Multiple"
I will try Single adn see what happens. 

[Lazzios]

I switched to single. And there is a display signla now! Resolution was messed up as normal with a new card, installed drivers which fixed it now waiting for the Reboot. If that switch was the issue, I vaguely remember fretting about that when I first installed it and I was sure I had it in the "correct" position for whatever reason. I'm going to try to put my 3090 back in after this and see if that works.

Thats good to hear, and good for me to know.

 

Please, whatever you do. DDU (display driver uninstal) your system before you decide which card you are going to end up using so you dont get wierd driver related issues.

Thank you so much for the assisstance. Is there a place you reccomend downloading DDU from?

[Alinz]

No worries, glad it worked!

 

Here you go Guru3d

Check this video from JayzTwoCents for instructions on how to use it.

Cool, thanks dude! Sadly the 3090 still seems cooked (4 redlights no signal). I'm not sure if that makes me happy that i did wast 2k on a new card or sad i coukd fix it haha.

Does that card have a dual bios? Try switching it!

[Lazzios]

So I tried to use the other BIOS on the 3090. Even used it as the 1st card after wiping the drivers, I can here windows boot up, but just get nothing on the display. Those RED lights on the card come on the moment the power is switched on. Most likely a cooked card. Gonna just install the 4080, and count my blessings it didn't get broke by my PC.

 

Thanks again for all the help!

[Alinz]

How old is that 3090 btw, maybe you could still RMA it.
