<human>:  How do I troubleshoot my computer?
<bot>: To troubleshoot your computer, start by checking that all the cables are properly connected. Check that the power button is working and make sure the monitor is turned on. Then reboot the computer and see if the problem is still happening. If it is, try running a virus scan to identify any potential issues. If that doesn't work, try resetting the computer to its factory settings or refer to your computer's user manual for further instructions.
