Generally we face issues with our PC, such as hardware/software issues. Many people know how to deal with software issues, simply uninstall it and reinstall the software, but mostly we cant identify the problem if it is related to any Hardware stuff. If suddenly the system restarts/ hangs up, we can simply restart and check if its working fine or it. If this still doesnt work and giving different beep sounds, dont get worry right away, each beep has a definite meaning and i conveys the caused issue and where it is located.
