You are mid-task when your software suddenly freezes, your mouse cursor transforms into a spinning wheel, and the top bar displays a cold notification: (Not Responding). This error indicates that the application’s main processing loop has become overloaded or locked up, halting communication with the operating system. Here is how to break the freeze.
Fix 1: Force Kill via Task Manager
When an application stops responding, clicking the close “X” box repeatedly often won’t work because the software can no longer register inputs.
- Press Ctrl + Shift + Esc simultaneously to launch the Task Manager.
- Under the Processes tab, locate the frozen application.
- Click on the app name and hit the End Task button in the upper right-hand corner. The operating system will instantly terminate the software’s memory thread.
Fix 2: Check for a Process Congestion Loop
Applications freeze when they are starved of system memory (RAM) or processing power (CPU).
- In the Task Manager, look at the top of the CPU and Memory columns. If either is spiking near 100%, your system is overwhelmed. Close down memory-heavy background applications—such as open web browser tabs or streaming services—to free up hardware bandwidth for your primary program.
