A "computer crash" occurs when a computer stops working suddenly and cannot perform any tasks. This can happen for various reasons, such as software bugs, hardware failures, or overheating. When a crash happens, you might see an error message or a frozen screen, making it impossible to use the computer until it is restarted. After a crash, it’s important to check for any lost work or files. Sometimes, programs like Microsoft Word or Adobe Photoshop have auto-save features that can help recover your data. Regularly backing up your files to an external drive or using cloud storage can also prevent data loss during a crash.
