Acer AN515-51: Unresolved and Ongoing Issues

For the Acer AN515-51 laptop:

The RAM and SSD have been upgraded.

Thermal paste was replaced.

Windows 10 was freshly installed on the new SSD.

The SSD capacity was increased and replaced with a faster one.

Initially, there was a single DDR4 2400 MHz 8 GB RAM module. Now it has been upgraded to dual-channel DDR4 3200 MHz, 2x16 GB = 32 GB.

(At first, the system did not boot due to the 3200 MHz speed not being supported by the motherboard and processor. Later, the frequency was manually adjusted to 2400 MHz via the BIOS.)

There is no visible hardware issue. The laptop detects all hardware correctly and boots up quickly. However, there are problems with sound, display, and web browsers (Chrome, Firefox, Edge). I believe these are software-related rather than hardware-related, but at this point, there shouldn't be any software or driver-related issues. All drivers are up-to-date, and I did not have these problems with the same driver versions before.

I suspected the new RAM or SSD might be the cause. I ran comprehensive tests including MemTest and did not receive a single error from either the RAM or the SSD. Initially, I encountered blue screen errors while using browsers (I have attached minidump outputs below), but I no longer receive those errors. However, the issues persist.

For example, when performing a task in Chrome, I receive a "STATUS_ACCESS_VIOLATION" error very shortly after. Visual artifacts appear in certain images or situations. As for the sound, strange noises occur (I will attach a video demonstrating this). When using Bluetooth headphones, the sound issue disappears, but the same issue happens with wired headphones as well.

To further troubleshoot, I booted into Linux Mint from a USB stick to test, and the exact same issues occurred there as well. Firefox closes abruptly, and there are artifacts in both sound and visuals.

I also removed the new RAM and reinstalled the original single-slot RAM, which has never caused any issues before. However, the same problems persisted even with the old RAM installed.

I have attached a video demonstrating the sound issue — this is the current situation:

There are no issues showing in my Device Manager. As I mentioned, all drivers are up to date, and I never had any problems with this driver before.
