II. How to fix “Unknown Hard Error” on Windows 10?

1. Perform a clean boot

When faced with an “unknown error” issue, the most efficient solution is to restart the computer. However, a normal restart may not be enough to resolve the problem. In such cases, a clean boot is recommended. This involves starting the system with only the essential drivers and startup programs, without any third-party software or plugins. The benefit of this approach is that it allows for easy identification of whether the issue is caused by the system itself or external software. If the problem persists after a clean boot, it could indicate a system error or a software malfunction.

Here’s how to perform a clean boot:

Step 1: Run the computer, press (Windows+R) keys at the same time to open the run window. Next type (msconfig) and press (OK) to open the system configuration interface.

Step 3: After that, switch to the (Startup), and click the (Open Task Manager) button. Next, select all applications that do not need to be started in turn, and click the (Disable) button.

If the problem is resolved after the clean boot, you can try to enable the previously disabled programs and restart the computer to troubleshoot it.
