Disable Windows Memory Diagnostics
If you run RTX for an extended period on Windows 10 with Windows Memory Diagnostics enabled, a memory access violation may occur and trigger a blue screen, causing the PC to restart.

In the left pane, expand Task Scheduler Library\Microsoft\Windows\MemoryDiagnostic.
In the center pane, right-click the RunFullMemoryDiagnostic entry and select Disable.
Similarly, right-click the ProcessMemoryDiagnosticEvents entry and select Disable.
Restart the PC.
