Sorry for the delay in reply. I've been offline.
The weird thing is that your system isn't logging anything when the problem occurs, which isn't common for software-related issues. But it makes sense that when Discord is open, it causes increased CPU and RAM usage, and this higher usage, even if slight, could be triggering some kind of problem.
In your question, you mentioned having the latest BIOS. Just to confirm: It's version "F6", right?
I suggest doing the following as well:
- Go to the Gigabyte website using the link below, download the latest Chipset driver, and install it.
https://www.gigabyte.com/Motherboard/A520M-K-V2-rev-10/support
Driver name: AMD Chipset Driver
Version: 5.11.02.217
(You will need to expand the Chipset category to find the mentioned driver.)
(Extract the ZIP file, and double-click the file "mb_driver_597_chipset_5.11.02.217" to run it. Then, follow the on-screen instructions to install the driver.)
I will explain why I suggested this:
The chipset is a vital component responsible for managing communication between the processor and external devices connected to the motherboard, such as the graphics card.
A compatibility issue with chipset drivers can make the system unstable to the point of experiencing BSODs or abrupt shutdowns, usually not in the way it's happening to you. However, I think it's a good idea to try.
Still, it's a good idea to check the RAM using MemTest86 when it's convenient for you.
Feel free to ask back any questions.
