Windows Repair & PC Troubleshooting
Computer troubleshooting starts with symptoms, not guesswork. This guide covers common Windows repair and PC problems and what information to collect before attempting a fix.
PC not starting or booting
Check power and monitor input, then note any exact message such as “No boot device” or a restart loop. Avoid changing BIOS/UEFI settings randomly. If a drive is missing from BIOS, repeated repair attempts may worsen a failing drive; consider professional diagnosis.
Windows installation errors
Confirm that important files are backed up and that installation media matches your intended setup. Installing or formatting the wrong disk can erase data. If more than one drive is connected, identify the target drive carefully before making changes.
Slow PC or laptop
Check free storage, startup applications, recent software changes and security alerts. Avoid unknown “driver updater” or “PC cleaner” downloads. Back up important data before major repairs.
Internet or printer not working
Check whether other devices can connect, verify cables and Wi-Fi status, and record any printer or network error. Install drivers from the device maker's official website when possible.
When to ask a technician
Seek qualified help for suspected storage failure, electrical damage, repeated boot loops, important inaccessible files or hardware faults. Confirm the cost and scope of work first.
