Here are some common computer problems
and
their troubleshooting techniques:
 Computer won't turn on:
 Make sure it's properly plugged in and the power outlet is functioning.
 Check the power supply and ensure that it's connected and functioning correctly.
 Check for any loose connections, particularly with the RAM or hard drive.

 Clean the inside of the computer to remove any dust buildup.
 Replace any malfunctioning fans or cooling systems.
 Avoid using your computer in extremely hot environments.
 Blue screen of death (BSOD):
 Restart the computer and try booting it in safe mode.
 Check for any software or hardware updates and install them.
 Run a virus scan to ensure that it's not caused by malware or viruses.
 Uninstall any recent software or drivers that might be causing the issue.
 Internet connectivity issues:
 Check your internet connection and router.
 Reset the router by turning it off and on again.
 Restart your computer.
