NVIDIA Laptop GPU keeps disconnecting
I recently started having problems with the availability of my installed NVIDIA GeForce RTX 4060 Laptop GPU. At random, the GPU will disappear from device manager and turn into a hidden device. The status messages indicates "Code 45", detailing that the hardware device is not connect to the laptop. Sometimes, a reboot of the laptop solves this issue, but this occurs very frequently.
I already tried the following:
*uninstall the device, and re-download the Nvidia drivers, but the issue remains.
*update drivers through device manager, but these are already the latest version.
*update windows, but already at the latest version.
*updating through GeForce Experience, but the Nvidia graphics drivers seems incompatible with my current windows version. I get this message when i try to download GeForce driver through the express installation.
Some specifications:
*Windows 11, version 23H2, OS Build 22631.4317
* Product ID: 00330-80000-00000-AA013
* Device ID: DC8C6B7E-DEFF-4A48-8826-089957BAE52B
i started noticing this issue frequently after the installation of windows 11. However, i'm not sure if it is related to that.

Same here, just had dell support out to change the motherboard but the issue still exists. I can't seem to get my 4060 to return at all now.

I had a similar issue. I ran Hwinfo and Furmark 2 stress test and revealed that the GPU had hotspots over 108 C just before disconnecting or going BSOD. I disassembled the laptop and changed the thermal paste. This seemed to fix the issue for now.
My laptop: Dell G15 5530
GPU: GeForce RTX 4050

@Roman A. Brother did this fix the issue completely? I also changed the thermal pasting. While the temps came down a bit. It still keeps crashing.
I'm wondering if I should finally just take it to a repair shop.

@Plz respond with solution
Update: I have a service contract and had Dell replace the whole motherboard including a new GPU. This solved the issue.
Turned out that the GPU was completely burned...

Anyone else having this problem
I have tried a lot of things and so telling from my experience. This issue could be indication of either hardware failure or software.
Now, in order to completely check for hardware fault or not. Use occt to run combined tests or vram tests. Then try testing using Furmark. If any error comes up. Then it's the hardware fault.
If not, then it is most definitely software fault. If I find a fix. I will surely share it here.

@user_b5bde6 Hi, no. While I fixed the hotspots on the GPU, I then started having some CPU cores overheating and crashing my laptop. I used ThrottleStop to disable turbo boost and limit max frequency. That fixed the overheating. I saw that other people who had the same problem suggested using thermal pads or liquid metal instead of thermal paste. Considering that the previous thermal element on my Dell G15 was liquid metal, I bought that, but I never had time to replace it. So far, I have had no crashes, even though I'm not using full CPU speed – it is enough for work and games.
