GPU not detected - Calling gurus one and all to share words of wisdom

[Ninja_Theory]

Hi guys, I need some advice please (I'm dying a slow death inside over this):

The situation: I moved my PC to a new case, fitted new case fans, new CPU cooler and new PSU. Before the move, all was well. After the move, my PC doesn't detect my GPU (Asus Strix 1080Ti) and it does not show in devices - but everything else is fine. Also, everything was fine before the move yesterday.

The question: Has anyone had a similar issue before where your GPU was not detected, and how did you solve it? Even if you haven't had this issue, can you share any words of wisdom or send some love and hope my way?

The troubleshooting performed to date: Used different PCIE cables from the PSU, used different PSU ports, used PSU to dual PCIE 6+2 pin as well as 2xPSU to PCIE 6+2 pin, re-seated the GPU a few times, re-installed Nvidia drivers, prayed to the gaming gods, used a whole lot of F-words.

Attached: Screenshots of the error I get: (a) thru Geforce; and (b) when re-installing Nvidia drivers

Does it pick up in Devices?

Nope. Only picks up the 8600k’s Intel 630.

Edit: Added device not showing update to OP.

on my mining rig one GPU stopped showing. and it was one wire that was burnt out. check ur cables and even the psu connector. I've had quite a few that burnt out. so I had to change the connector into psu and the cable.

I had this problem once with a GTX580, moving to a different PCI port seemed to fix it.

Perhaps your new case has a slightly larger depth to the M/B so when installing the card, it's not making proper contact with the PCI-E slot. Might be imperceptible.
Reseating it might not work. I've seen this with some cards and cases over the years.
Ideally you would want to test the GPU in the board but not in the case thus eliminating this potential problem.
A hassle i know but can't think of other reasons besides faulty cables which is unlikely as you were just using it in the previous build.

PS: I see you are using a different PSU not the same one . You need to confirm your old PSU works fine in the new system .
Just piggyback it to the new build . Naturally if it works then your new PSU has a problem or the cables do

There was a windows update lastnight not sure if it could be related have you tested other pci e slots ?

I have a mining rig in my possession which had an issue mines few hours and then stops carried on for weeks guy didnt bother checking "risers" i tested each gpu (6 hours) and turns out 1 riser wiring burnt overload of current as the 1st gpu was spinning then no display then it would mine lol

Revert the update of windows and try testing outside of the case and see my 1 mobo was the culprit booted with onboard graphics/ wouldnt see a gpu .

Are you using gpu for display or on board display ?

Have you tested the GPU in another PC? Do a process of elimination. If you know the GPU works then that's one less problem to worry about. In my experience it's either the GPU, Power or the PCIe slot on the motherboard.

 

[Maximums_Rickimus]

Wait what do you mean you used 2xPSU to PCIe 6+2? What PSU are you using? Are you using an adapter that works from the 4 pin molex to a 6+2 pin adapter?

 

[Ninja_Theory]

Thanks guys, busy troubleshooting the ideas here. Very frustrating. I’m wondering if my gpu hasn’t maybe given up the ghost. I started making a fan noise this week which is why I wanted to move my rig this weekend - to test it thoroughly before sending it back. It’s 5 months old. Bought it new.

On board. PC not seeing the gpu. Did try - but nothing.

Probably a case of poor wording by me.

What I meant is I tried going 6-pin pcie from psu to 6+2 on gpu. Then another 6-pin pcie from psu to the other 6+2 on the gpu. Before that I had it running from a single 6-pin pcie on the psu to a 6+2 splitter (so I could use the single cable from the psu).

Seems like the new motherboard is somehow defaulting to the on-board GPU. Send a screenie of your device manager please @Madala_ZA - it might just be a stupid bios setting that's causing this.

And yes, I know it's the same hardware just a different case. But I managed ~40 rigs all with identical hardware and configs and each one seemed to behave in its own unique way. It fucked with my OCD.

Gonna have to. Been troubleshooting this fucked up since last night so will do that when I have energy again.

Foxxy and Siltech both offered to help.

Will send shortly. It’s not a new mobo. Same mobo. Asus Z370 Maximus Hero X. I also reset the bios but no change. Bios doesn’t see the gpu either.

 

[Ninja_Theory]

@GaaTY bios doesn’t see the gpu though.. not sure how to send screenie of bios [emoji85]

 

[GaaTY]

@Madala_ZA a picture with your smart phone will do

 

[fatty]

Phone @foxxxy or @SILTECH and take some [emoji481].
Test gpu in another rig and go from there

Good luck

From BIOS and from Device Manager. I can see it’s defaulting to the Intel 630. But that’s a given because the system doesn’t see the Strix:

Edit: I didn’t mention that the GPU lights up and the fans spin.

 

[Petester]

Until you swap parts, test in other systems etc , there is nothing more to do on your system.

And you have tried BOTH your PCI ports?

 

[SILTECH786]

No beer needed but you will be offered sweetys when and if you decide to come round, keep me posted cool ciao

 

[Ninja_Theory]

Not yet, but I will. Too lazy now after troubleshooting till after 3am and then again most the day today although yesterday she was just fine in this bottom pcie slot.

Agreed, thanks guys. Will reach out to fox or siltech (have already) and set up a date.

You’re going to hate yourself for not testing it in the other PCI port first.

It might just be a faulty port

You're right. I will test it later or tomorrow.

Tested. Same
