Why Restarting Your Computer Solves Problems

One of the most common questions IT support personnel ask is, “Have you tried restarting your computer?”

And the most common answer we get is, “Of course, I turn my computer off every night!”

But there is a difference between simply turning off your computer and restarting it.

Restarting solves common PC issues

What happens when you restart your computer?

Restarting a computer often solves problems because it performs a complete reset of the system, which can clear out any temporary issues that may be affecting the system. Here are some reasons why restarting a computer is more effective than shutting it down:

  • Clears system memory:

    When a computer is restarted, it clears out the system memory (RAM) completely. This can help to clear out any temporary files or processes that may be causing issues with the system.

  • Stops running processes:

    Restarting a computer stops all running processes and services, which can help to resolve issues that may be caused by software conflicts or other issues with programs running on the system.

  • Reinitializes hardware components:

    Restarting a computer can also help to reinitialize hardware components such as the network adapter or graphics card, which can help to resolve issues related to these components.

  • Reloads system software:

    Restarting a computer can also reload system software, which can help to ensure that any updates or changes to the system are properly applied and functioning correctly.

Shutting down a computer, on the other hand, simply turns off the power to the system. This can be useful for completely powering off a computer for extended periods of time, but it does not perform the same type of reset that a restart does.

What are the different actions computer will perform

  • 1

    Closing all open programs and saving any unsaved data.
  • 2

    Flushing data to the hard drive to ensure that all data is saved.
  • 3

    Unmounting file systems and disconnecting from any external devices.
  • 4

    Stopping system services and processes.
  • 5

    Turning off the computer's hardware components in a controlled manner.
  • 1

    Closing all open programs and saving any unsaved data.
  • 2

    Flushing data to the hard drive to ensure that all data is saved.
  • 3

    Unmounting file systems and disconnecting from any external devices.
  • 4

    Stopping system services and processes.
  • 5

    Turning off the computer's hardware components in a controlled manner.
  • 6

    Powering on the computer's hardware components and reloading the system software, including the operating system and any startup programs.

As you can see, a restart involves an additional step of powering on the computer’s hardware components and reloading the system software, which is not performed during a shutdown. This allows the system to perform a complete reset and can often help to resolve issues that may be affecting the system.

How can I check when my computer was last restarted?

One way to check your computer’s last restart time is by using the Command Prompt.

  • Press the Windows key + R to open the Run dialog box.
  • Type "cmd" and press Enter to open the Command Prompt.
  • In the Command Prompt, type "systeminfo" and press Enter.
  • Wait for the system to generate a report on your computer. Look for the "System Boot Time" line to see the date and time when your computer was last restarted.
To check when your Windows computer was last restarted through the Task Manager, you can use either of these methods:
  • Right-click on the taskbar at the bottom of your screen and select "Task Manager" from the menu. Alternatively press the Ctrl + Shift + Esc keys together on your keyboard to open the Task Manager window.
  • In the Task Manager window, click on the "More details" button at the bottom left corner to expand the Task Manager view.
  • Click on the "Performance" tab at the top of the window.
  • In the left pane, click on "CPU", and then in the right pane, look for the "Up time" field to see how long your computer has been running since the last restart.

It may seem like a simple solution, but restarting your computer can often solve many issues.
