How do I troubleshoot my computer if it's not starting up properly?

First, check the power cable connected to your computer to make sure it is plugged in firmly. Then, try restarting your computer by pressing and holding down the power button for 10 seconds or more. If the computer still won't start up, you may want to try connecting your computer to an external monitor to check if an operating system is beginning to boot. If that doesn't work, you may need to reset the BIOS or check the RAM, graphics card, and processor components.
