You'll need a USB that's correctly formatted, and has a bootable version of the desired operating system.
Most importantly, you'll need to ensure that your BIOs are set to boot from a USB drive.
(If you're running off a solid state drive, with Windows 10 in particular, it can be tricky to get to the BIOs menu -- fortunately, that shouldn't be an issue with the system you're using, unless an SSD was installed afterwards)
You can also diagnose certain issues and troubleshoot by using a bootable toolkit, in order to see if there's damage to the hard-drive or file system.
However, if you never see any text display on the screen during boot-up, then it's likely to have much more extensive issues than just the operating system, or hard-drive.
Best of luck.
