I'm helping troubleshoot a brand-new Windows 11 PC with a Ryzen 5 5600X, RTX 5060 8GB, ASUS Prime B550M-A WiFi II motherboard, 16GB DDR4-3200 memory, 1TB NVMe SSD, and a 750W power supply. Windows works normally for basic tasks, but launching games such as Counter-Strike 2 or Minecraft quickly makes the entire system unstable. The game stutters, the mouse becomes extremely slow, Windows lags heavily, audio through the headset crackles or becomes distorted and very loud, and the microphone may disappear. Sometimes the whole computer almost freezes. Windows, drivers, GPU software, and settings have already been reinstalled or updated, and the motherboard has even been replaced twice. Since the components are new, what should be tested first to isolate the cause? Are there useful monitoring tools, stress tests, Windows logs, or BIOS checks that could reveal whether the issue is related to CPU or disk usage, memory settings, the GPU, chipset or USB drivers, power delivery, or another component?

Check the memory configuration in BIOS and in Task Manager. Make sure both sticks are detected and that the memory is actually running at its rated 3200 MT/s rather than a much lower default speed. You may need to enable the board's memory profile, but if instability appears after doing that, test with the profile disabled or run the RAM at a conservative speed.
Watch Task Manager or a hardware monitor while starting a game. Check whether CPU or disk usage suddenly reaches 100%, and also keep an eye on temperatures, clock speeds, and memory usage. A page file that is disabled or misconfigured could also make the system behave badly under load, so confirm that Windows-managed virtual memory is enabled.
We'll verify the detected capacity and speed, then test both the rated profile and default settings to see whether the behavior changes.
