    Hello, Alexander Blankenship.

    The problem is caused by one of the components of the Gigabyte Control Center program. And many users have a similar problem. To check, delete this program and observe the PC operation for at least one day. Write about the result.

    The crash shown in Event Viewer is an unhandled .NET exception inside the Gigabyte Control Center component GbtCloudMatrix.exe. The exception is System.IO.FileNotFoundException, which means that this specific Gigabyte app is trying to access a file that does not exist (or is not accessible) and is not handling the error, so the process terminates. The faulting module KERNELBASE.dll is just where Windows surfaces the .NET exception; it is not the root cause.

    This explains the application crash, but the black screen and system becoming unusable indicate a broader system or driver problem. The context shows that unexpected restarts/black or blue screens on Windows 11 are typically caused by hardware, drivers, or low‑level software, not just a single app crash.

    Use these steps to troubleshoot on Windows 11:

    1. Check for stop codes or BSODs
      • If the system ever shows a blue or black screen with a stop code (for example, PAGE_FAULT_IN_NONPAGED_AREA, MEMORY_MANAGEMENT, etc.), note the exact code. These codes help identify whether the issue is GPU, storage, RAM, or driver related.
      • If the screen is just black with a cursor and no stop code, refer to the dedicated guidance for blank/black screens in Windows (linked from the stop‑code article below).
    2. Update or repair Gigabyte Control Center
      • Since GbtCloudMatrix.exe is part of Gigabyte Control Center, uninstall it from Apps → Installed apps, then download and reinstall the latest version from Gigabyte’s support site for the motherboard or laptop model.
      • If the crashes stop when Gigabyte Control Center is removed, the issue is in that software. In that case, either keep it uninstalled or reinstall only if a newer version is available.
    3. Update graphics and chipset drivers
      • Install the latest GPU driver (NVIDIA/AMD/Intel) from the GPU vendor or the PC/motherboard vendor.
      • Install the latest chipset and storage drivers from the motherboard or OEM support page.
      • Out‑of‑date or faulty drivers are a common cause of black screens and unexpected restarts.
    4. Check for Windows stop‑code guidance
      • For any unexpected restarts or BSODs, follow the official troubleshooting steps for Windows 11 stop‑code errors: identify the stop code, remove or update problematic drivers or software, and check hardware.
    5. Test hardware if problems persist
      • If black screens continue even after removing or updating Gigabyte Control Center and drivers, run hardware diagnostics (RAM test, SSD health check, GPU stress test) using tools from the PC or motherboard vendor.

    If the only symptom that remains after removing or updating Gigabyte Control Center is the System.IO.FileNotFoundException in Event Viewer, then the fix is specifically to repair or remove that application; it is not a Windows or .NET runtime bug.
