My laptop crashed yet again after updating graphics drivers

Diagnostic results: BSOD - Google Drive

I'm using Acer Nitro 5 AN515-56 Windows 10 x64.

Occurance: Like all my previous posts, I see BSoD only when installing new gpu drivers through NVIDIA Experience. Last 3 drivers I installed happened to crash it near the end of usual installation. I'm met with the following screen:

After force shut down, when I boot it back up, the latest drivers appear to be successfuly installed. The following is the snapchat of the current version of the driver:

One instance I recall might be the clue is before all of this started happening, I had the laptop cleaned with compressed air. I kind of did it in a rough way, not regarding I might damage the fans. They spinned and all the dust just got out. Could the components be damaged by the air and result in these issues? If so, how can I check it or even fix it if that's the case?

Since then I've been hearing very mild buzzing from one of the fans at some occasions, but it stopped more than a month ago. The temperatures of components were never lower (averaging in 50 C with tops about 80 C). I have no other suspicious experiences. Hardware nor software. Just this.

Please help me. The laptop is about 2 years old now and still in almost brand new condition.

The problem in that dump appears to be with the Nvidia driver nvpcf.sys, which is part of the Nvidia graphcis driver package. It unloaded without closing the resources it had open...

IP_MODULE_UNLOADED:
nvpcf.sys+1d7d0
fffff807`19a7d7d0 ??              ???

That's why you got the DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS BSOD.

Laptops often use customised graphics drivers, both for the dGPU and the iGPU - which work hand-in-hand in a laptop. The generic drivers from Nvidia and Intel don't contain these customisations and often cause problems on laptops.

I suggest that you uninstall the current graphics drivers, using Device Manager for the Intel graphics driver and DDU for the Nvidia graphics driver, and then download and install the Intel and Nvidia graphics drivers from the Acer website for your AN515-56 laptop. They are dated 2021 but we know for certain that they are fully compatible with each other and with your laptop.

If it BSODs on these drivers please run the SysnativeBSODCollectionApp again and upload the resulting zip file.

BTW. I also note that you're running with mismatched RAM sticks. One is a Crucial CT8G4SFRA32A.M4FF and the other is a Micron 4ATF1G64HZ-3G2E1. RAM should only be bought in packs of matched sticks to ensure that all the timings align. I don't believe that this is related to your current problem, and you may have got away with this mismatch so far, but just be aware that it may come back to bite you in the future.

Thanks. Will try reinstalling older drivers and report back if anything unusual happenes after that.

Regarding RAM, the one came included with laptop purchase while the other one I bought few months after getting the laptop. Since both come with same capacity of 8 GB, I thought different manufacturers wouldn't be that much of an issue.

With RAM the internal timings are critical.

I hope you found a solution because I'm having the exact same problem. I even have a nitro 5, and mine also says the latest version of 555 whatever.
