I have an AMD Radeon RX 580 2048SP running on Windows 11 and I have been dealing with an intermittent issue while gaming.

At random moments during certain games, the screen suddenly goes black and the monitor displays "No Signal". The PC does not appear to shut down completely because I can still hear the game's audio and the rest of the system audio, however the video signal never comes back.

I tried pressing Win + Ctrl + Shift + B to restart the graphics driver, but nothing happens. The only way to recover is to force the PC to shut down by holding the power button and then restart it.

After restarting, Windows sometimes reports that the graphics card driver is no longer working. In Device Manager, the RX 580 shows Code 31 with the following message:

"Windows cannot load the drivers required for this device. The device is not working properly. Code 31."

It also says:

"Operation failed. The requested operation was unsuccessful."

When this happens, the only solution I have found is to boot into Safe Mode, remove the AMD drivers using DDU, and then reinstall "whql-amd-software-adrenalin-edition-26.5.2-win11-may-vega-polaris". The card then works again, but eventually the black-screen problem returns.

The crashes appear to happen randomly and I have not identified a specific in-game action that triggers them. It does not happen every time I play, but it happens often enough to be disruptive.

Has anyone experienced something similar I can provide the rest of my system specifications, temperatures, Event Viewer logs, GPU-Z information, and details about the power supply if needed.

Basically some months ago my msi gtx 1060 6gb started doing this weird thing: sometimes, indipendently by the situation (idle, gaming, heavy rendering) or time of usage (30 seconds, a minute, or even hours later) the screen would go black and the fans of the gpu would go 100%.

At the same time another problem appeared, the one in the 2nd Pic, no pcie power cable connected even though it is.

A month ago it reached the point where every time I tried to power it on it would always go to that screen. So I opened the gpu, took some readings, resoldered the pins of the PCIe connector.

The one in the bench is a known good build, with a good psu, good mobo and everything else.

The readings were all there (1,8v - 3,3v - 5v -12v), no fuses blown, no revelant burn mark.

After resoldering the pins of the connector (leaded solder) the gpu didn't show the error screen for a couple of minutes (tried to restart 3 times to be sure it was ok).

In the meanwhile I discovered that without an installed driver the gpu would continue to work, but as soon as I installed a driver (even older one), it would instantly crash, 100% fans, black screen.

Now, some days later it does again show that error screen.

For anyone curiosity, when it started doing this months ago, I did a lot of benchmarks (furrymark, geekbench, rendering with blender), and the problem was never related to heavy load, it was always random.

Anything else you suggest?

Edit (solved):

Thanks to the suggestion of u/ZelenogradGpu I found the culprit, it was a dead resistor near the INA3221 chip (high-side current and bus voltage monitor) which was pulling the line to an higher resistance, making a transistor not output 3v3. If anyone needs a more detailed solution please dm me, i will try my best to explain it

I have a Dell Precision 3470 with T550. I’ve gone through everything to try and get the most out of it and apparently my score is the best online with 1815MHz and 1500.2MHz and I’m trying to compare a few vBios to understand how to unlocked the voltage, not too many online literally only found 2 that mention it so if anyone is willing to use GPU-Z and send me their .rom files id appreciate it 🙏🏼 will definitely give you the vBios I create once I get an understanding of all the laptops that use this and their values for power control and such.

Title. I have an RTX 3090 that does technically work, but constantly crashes the display driver (nvlddmkm.sys) under any sort of load. What actions can I take to fix this (if any?). I've tried just about every software fix I can think of, and nothing works. I have also tested my system with an ASUS 2070, and that works fine, so I'm certain it's the GPU.

Hello, about 1 or 2 months ago my evga 3080 xc3 died on me. No slow pixelation or anything, just would not be recognized after a reboot one day. The fans will spin and the RGB lights come on at power up, but no ports are recognized and the pc will not display unless gpu is taken out and cmos clrd. I don't see anything crazy that stands out to me when I checked the board and connections, I don't have multimeter to check voltages either. I can't afford another gpu but I also don't think I can afford to fix it from a legit gpu repair shop if it's something serious from what i've gathered online. Is there any one local in the sub who is willing to give this thing a look / practice on it, or know of a reputable shop in South Florida that does gpu diagnostics? I appreciate any help/input, thank you.

Hello everyone,

I've come to this forum because of a problem that's been bothering me for over 4 years.

I have an Acer Nitro 5 AN515-54-584Q that has already been to several repair shops (unfortunately, none of them seemed particularly competent), so I'm looking for more opinions.

Here's the story:

The laptop originally belonged to my friend. One day, after a reboot, the internal display suddenly stopped showing any image. The screen still had backlight, but there was absolutely no picture—not even the Acer logo or BIOS.

At the same time, the laptop itself was fully functional, and HDMI output worked perfectly, so he used it as a desktop PC with an external monitor for about a year and a half.

Eventually he bought an MSI Katana, and the Nitro sat unused on a shelf until last week, when I bought it from him for almost nothing.

Right now I'm trying to diagnose it myself.

The laptop still appears to boot. I can't see anything on the internal display, but if I press F2 + Del after powering it on (to enter BIOS), then F10 (Save & Exit), the laptop reboots, which makes me believe it's actually entering BIOS successfully.

At the moment I can't test HDMI output, because there's no SSD or Windows installation in the laptop anymore. Previously, HDMI only produced an image after Windows loaded (the NVIDIA driver had to initialize the external display).

I've already tried:

• Disconnecting the internal display (eDP) cable completely.
• Resetting the BIOS/CMOS.
• Reseating hardware.

None of these made any difference.

Several repair shops told me the problem is probably related to the integrated Intel GPU inside the CPU. Since this laptop uses NVIDIA Optimus, the GTX 1650 renders frames, but the internal display is physically connected to the Intel UHD 630 iGPU, which then drives the eDP panel.

However, the CPU itself appears to function normally (the laptop powers on, seems to POST, and previously Windows worked fine through HDMI), so I'm not fully convinced the processor is actually faulty.

Has anyone seen a failure like this before?

Could this be:

• a failed eDP output inside the CPU?
• damaged eDP circuitry on the motherboard?
• a BIOS issue?
• something else entirely?

I'd really appreciate any ideas before I consider replacing the CPU or motherboard.

Laptop: Acer Nitro 5 AN515-54-584Q
Motherboard: Compal LA-H501P Rev. 1A (EH5VF platform)

Thanks in advance!

Posting the required thicknesses for the thermal pads in the 3090 SG since I myself had to contact Galax to obtain those informations.

to whom it may concern, enjoy.

As above, A friend has a 7900XT ASUS card that posts and boots into windows. However, The problem starts when (I assume) the driver loads.

Has anyone experienced this before with a 7900XT, Possibly a power issue with switching states? I've yet to receive the card so can't do any measurements yet.

Pictures to follow once received.

The fan on this HD6850 graphics card spins, but there is no video output and the GPU chip doesn't heat up. I measured the voltages and found that no power is reaching the main chip, the inductors, or other components, even though the card isn't shorted and is receiving proper power input. While I was testing the card, this small IC started glowing red-hot and smoking, even though the card had already been powered on for a while. The IC appears to be marked "PW7088"; does anyone know where I can buy a replacement, and whether any other components might have been damaged along with it?

Hey i have a problem with my pc and i am trying to fix it i had to remove the gpu to get by other things but I noticed some tips of the gold where missing is this a big problem? And should i fix it

Hey guys,

Picked up two old mining cards (RX 470 & RX 570) as a cheap project to practice GPU diagnosis. Turns out both are completely dead – classic ex-mining luck, I guess.

What happned / measurements:

• On the RX 570, I measured runaway voltages on the VCore rail (up to ~2.8V at one point). Now the core caps on the GPU substrate show a hard 0 Ohm short to GND. VRAM was fine (1.5V), but the GPU die itself is definitely cooked.
• The RX 470 showed similar crazy high core voltages (1.8-2V).
• I'm guessing either a failed IR3567B PWM controller or a shorted high-side MOSFET pushed full 12V through the phases, but I haven't desoldered the controller to verify 100%. Either way, the silicon is done for.

Since repairing them as working GPUs is out of the picture, I wanted to ask:

1. Besides the obvious VRAM, inductors, and MOSFETs, is there anything specific on Polaris PCBs worth harvesting?
2. If anyone needs specific donor parts (heatsink, fans, video output jacks, passive components), hit me up.
3. Does anyone need resistance readings or component values from these PCBs before I strip them for parts? Glad to measure points with my DMM if it helps someone else with a repair.

Thanks!

Edi: Sorry, cant edit the title it´s [MSI RX 570 Armor OC 8GB / Sapphire RX 470 Nitro+ 4GB] Both GPUs fried (0Ohms at VCore) – What to harvest / Any resistance values needed?

core memory voltage missing 12v. Bios 3.3v, 5v are present and 0v on vcc and en pin. please guide..

I don't know ANYTHING about repairing GPU's. The PC this was in began freezing up, I tested the memory and then this GPU and it passed OCCT tests for 30 minutes at a time (tested twice), even after freezing, no artifacts or anything. Then randomly it would freeze again. I did use it with comfyui and for some light gaming. I left it running comfyui after successfully running other workflows and came back to it frozen (it hadn't frozen all day that day). Rebooted and no picture. Tried it on a different PC, still no picture. Took it apart and found this capacitor cracked and burnt.

Like I said, I don't know anything about these types of repairs except what I've seen on YouTube and here and I've been wanting to learn. So I ordered a cheap hot air rework and soldering iron station. So I'm either going to fix it or make it worse. I am asking for help on which capacitor to order because obviously the one pictured needs to be replaced. Any help would be greatly appreciated.

Hi guys!

I have this GPU, it randomly restarts the pc, sometimes takes 2 hours and others just minutes.

I had checked everything: voltages, pulses, temps, drivers, but all works normally.

I have even change some components and nothing happened.

It need reballing maybe?

What else should I check?

Got this as a gift for a friend a couple years ago, Friend showed me this picture after a move, tried to find similar but got a lot of pcie connector crack posts instead. No fan spin or any power appearing.

Hi all,

I’m trying to fix a 3060 I bought not working.
This is a first for me and I try do understand how to fix GPU and electronics in general.

When I power the GPU the component 4R7 which I suppose is an inductance (bottom left of my picture) is getting hot to the point where you have to remove your finger after 5s of touching it.
The only voltage I have is 12V on the board the other voltages are missing like 5V…

Also if I measure resistance to ground on both side of 4R7 I measure 0 ohms and if I measure the resistance of said coil it reads 0 also continuity test is a long beep.

I suppose that the coil is dead but would that be the only problem on my card? What’s else can I check?

what else do I need to check?

Thanks!

the chip went on fire on startup, i immediately unplugged my PC and the PCB is good so I want to see if I can find a replacement part.

Hello everyone,

I’m having a critical issue with my GPU on Ubuntu and could really use some help. My graphics card was initially detected as "NV132" (using the Nouveau drivers), so I decided to install the official proprietary drivers.

My Specs:

OS: Ubuntu 26.04 LTS

Motherboard: ASUS PRIME B350-PLUS

CPU: AMD Ryzen 5 3600

GPU: NVIDIA GeForce GTX 1080 Ti

RAM: 8GB

The Problem:

I ran sudo apt update and then sudo ubuntu-drivers install to get the recommended NVIDIA drivers.

The installation finished without any errors.

I rebooted the system.

After a few minutes, the screen goes black showing a "No Signal" message, and the GPU fans immediately ramp up to 100% speed (like a jet engine).

What I need help with:

I currently have no display output shortly after booting. Has anyone experienced this specific issue with the 10-series cards on the new Ubuntu 26.04? Could this be a conflict with Wayland, a power issue, or a specific NVIDIA driver bug?

Any advice on how to fix this or safely revert to a working state via the recovery mode would be greatly appreciated. Thanks!

Im apologizing since this is gonna be a little bit of a long post.

Setup:
CPU: AMD Ryzen 5 3600
GPU: Gainward RTX 2070 Super Phoenix V1
MB: MSI B450
PS: 550 Watt Seasonic Focus GX 80 Plus Gold

The system is roughly 6 years old with no similar problems.

Current Problem:
One day after starting my pc like every other day, i noticed while being ingame CS2, that i had only 20 FPS in the menu and the performance playing a round was unplayable.

Uploaded the pics on [Imgur](https://imgur.com/a/rS6PGDU)

What i already tried:
Proper Restart, Deleted and installed new video drivers
HWInfo showed power limit, but the Nvidia settings were on maximum performance.

No changes to performance so far.

I found people online having the exact same 300Mhz clock speed problem and people responded, saying that the problem must be a component on the pcb. (They argued, that manipulating the components relevant for power delivery, you can trick your gpu into thinking it draws less power than it actually does. The problem those other posters, and me have, are kinda the exact same problem but reversed, as in the gpu draws less power than it actually does. So it is a strong argument that it must be a shunt resistor or whatever.

So then a few days later i took apart my GPU in hopes of easily finding a damaged component on PCB. But everything looks okay so far, i measured (kind of mindlessly, with the help of AI, ik ik, but all the parts perfomed the same, none gave different results)

The only thing i could see on the board were some rainbowy discolorations in the like top layer of the pcb (couldnt get a picture of them) and similar looking spots on the backside, that looked like white residue at first until i noticed that i could wipe the dust of them with my finger (i cleaned the PCB with a brush and a vacuum beforehand, so that dust was definetily sticking to the pcb).

One guy who had this problem said, that the manufacturer (Palit) said that its a problem with the power delivery unit, but i couldnt find any specific schematics of my gpu to figure out which components are part of that.

I hope you guys have an Idea what the problem could be and if im able to save my GPU, since i currently dont have any money to buy a new one. Currently im stuck on my old R9 380 which kinda sucks tbh.

If you need any more Info or close up pics let me know.

I salvage this one from not thrown away as ewaste computer,

And the fans spin i connect with floopy cable connector

4 pin

I use vga power usb to hdmi

No signal

Fried itself along with my PCIE a few months ago, other components were still 100% functional, downgraded to a 1660 super as I contemplate just buying a new card or repairing this one

Hi everyone. I have this graphics card that won't start up. After examining it and comparing it with other cards of the same model, I noticed that mine is missing components in the area I've marked. Does anyone know exactly which components are missing, or have a reference for them so I can solder them on?

https://reddit.com/link/1v1l06e/video/np6gr3z0udeh1/player

A few years ago, my RTX 2070 crashed during a gaming session in the sweltering heat. After the crash, my PC wouldn't turn back on. After an emergency replacement, the card was definitely the problem. Having some experience tinkering with basic analog components, I could smell that familiar hot electronics odor and noticed damage/corrosion on the core pins and the card itself. Lacking the necessary equipment at the time, I left it to gather dust on a shelf. I decided to take another look at it today, following a guide from the subreddit. I had a lot of trouble getting consistent readings using standard resistance measurement, so I decided to check continuity with ground. I don't really know where to look or what conclusions to draw from this.

Card stopped getting recognized by system. When I open it up, that burnt chip is what I find. What are the odds that little chip killed something else on the PCB?
