Thanks for the screenshot.
You're totally right that Realtek doesn't show up in the main error summary! Standard automated reports usually blame tcpip.sys (Windows' built-in networking system) because that is where the system officially gave up and crashed.
However, the actual trigger is hidden in the STACK_TEXT section, which shows the chronological list of commands right before the blue screen.
If you look closely at that stack, you will see rt640x64. That is the specific file name for your Realtek PCIe network driver. What happened here is a classic DPC_WATCHDOG_VIOLATION: the Realtek driver held up the processor for too long while handling network data, causing Windows to time out and crash while trying to process it through tcpip.sys.
I'm attaching a screenshot highlighting exactly where it is in the log so you can see it!
Based on the information in the screenshot you shared, the adapter is currently using an old driver, likely a generic one. This could well be the root cause of the crashes.
I suggest performing a clean installation of the latest driver provided by ASRock for your motherboard's network adapter. That should resolve the issue, provided there isn't another driver secretly interfering with the Realtek driver. Follow the steps below:
1 = Before starting the procedure, download the latest network driver from the ASRock website.
https://www.asrock.com/mb/AMD/A520M-HVS/index.asp#Download
Driver name: Realtek Lan driver ver:10.060.0615.2022
2 = Uninstall the current driver:
- Open Device Manager;
- Expand Network adapters;
- Right-click on the adapter Realtek PCIe GbE Family Controller and select Uninstall device;
- On the confirmation screen, check Delete the driver software for this device and click Uninstall;
- Restart (not shutdown) the PC.
3 = Then, extract the ZIP file you downloaded, double-click the file setup to run it, and follow the on-screen instructions to install the driver.
4 = After completing the driver installation, restart (not shutdown) the PC.
See if the system runs stably after doing this.
If the crash occurs again, please share the minidump it created.
