One easy way to get a computer's applications unfrozen is to open the Task Manager, click the Processes tab, and close programs that are not working to free up system resources. Often a computer freezes because one or more programs is taking up nearly all your CPU or RAM.
- Open Task Manager
To open Task Manager, press Ctrl + Alt + Delete or Ctrl + Shift + Esc on the keyboard. The Task Manager takes priority over any other processes, so give it time.
- Click the Processes tab
The Processes tab in Task Manager shows every process that's running on your computer along with how much RAM and how much processing power they're using. You can also click on the Performance tab to see what system resources are available. If your computer is frequently locking up, the CPU is likely spiked to 100 percent usage.
- Close processes that are not working
Click on a process to highlight it, and click the End Task button at the bottom right of the Task Manager screen. Carefully select which tasks you end, as some of them are critical Windows services. As a rule, only end processes in the Apps section of Task Manager. Freeing up system resources should make the computer responsive again. If not, press and hold the power button for about five seconds. Leave the computer alone for 10 seconds, and turn it back on.
