The issue described involves a Windows 7 computer that intermittently freezes, allowing mouse movement but no interaction with the system. This behavior suggests a potential problem with the explorer.exe process, which manages user interaction with the operating system. It may be caused by a third-party software conflict. To troubleshoot, it is recommended to monitor CPU usage via Task Manager during freezes, restart the computer in safe mode, and disable unnecessary startup programs using msconfig, keeping only antivirus software active. If the problem persists, killing the explorer.exe process and restarting it may provide a temporary fix. Additionally, hardware issues, such as a malfunctioning mouse, could also be a factor, as one user experienced similar symptoms that were resolved by replacing their mouse.
