For whatever reason, you may want to crash your computer. Using your PC's Notepad app as a platform, you can create a simple .bat (or "batch") file that creates an infinite loop of opening Command Prompt windows; this will rapidly consume your computer's RAM, causing it to temporarily crash. As a general rule, you shouldn't intentionally crash any computer but your own, no matter how temporary the crash is.

How to Crash Your PC

  1. Open the Notepad app and type “@echo off.”
  2. Hit “Enter” and type “:crash.”
  3. Hit Enter again and type “start.”
  4. Hit Enter again and type “goto crash” as your final line of code.
  5. Save your file as a batch (.bat) file.
  6. Right click the file and select “Run as Administrator.”
  7. Restart your computer to end the crash cycle.

  1. You can do this by typing "Notepad" into the Start search bar and then clicking the pertinent app, or you can access it manually by opening the Start menu, scrolling down to "Windows Accessories", and opening the Notepad app from there.
    • You can also right-click your desktop, hover over "New" in the context menu, and select "Text Document".
  2. This is the first line in your batch code; it prevents your .bat file from cutting itself off. [1]
    • You'll need to tap ↵ Enter after each line of code.

  3. The ":crash" command creates a loop point.
  4. This will prompt your .bat file to open a Command Prompt window.
  5. This is your fourth and final line of code, which will prompt the .bat file to return to the loop point; in this way, your .bat file will continuously open Command Prompt windows, thus eating up your system's RAM.
  6. Text files have easily-edited file extensions. To set up your file as a .bat file:
    • Click "File" in the top left corner of Notepad.
    • Click "Save As...".
    • Click the "Save as type" field at the bottom of the "Save" window.
    • Click "All Files" in the drop-down menu.
  7. You can do this by typing any name into the "File Name" field. Be sure to type ".bat" (excluding the quotes) at the end of whatever name you choose.
    • If you can't come up with a name, "mobile.bat" and "cave.bat" are both excellent choices.
  8. You are now ready to execute your .bat file!

Executing Your Batch File

  1. While the .bat file won't actually harm your computer, you will have to restart your computer in order to end the .bat cycle. This means that you might lose progress on any work left open and unsaved.
  2. Again, you'll want to save any work done here before exiting your respective browser windows.
  3. This will prompt a context menu.
  4. This will start running the .bat file; your screen should suddenly be full of duplicating Command Prompt menus.
  5. Since you won't be able to move your mouse after a few seconds of the .bat running, you'll have to shut down your computer by holding down the power button.
  6. This should start up your computer; you may have to wait for a few seconds after shutting down before restarting.

  • Question
    How come every time I click "run as administrator", it doesn't work and takes me back to Notepad?
    Community Answer
    Right click the batch file, and then click "run." It doesn't need to be "run as administrator."

      • On Windows 10, running the .bat crash will cause several processes in your computer to glitch, thereby boosting your disk activity to nearly 100 percent and slowing down your computer. You can end the relevant processes from within Task Manager ( Alt + Ctrl + Delete ).
        Thanks

      • While a batch file is entirely harmless, creating and executing a file designed to crash a computer on any machine other than your own may be met with strict consequences.
