All computers used for gaming purposes should be optimised regularly at least once a month, especially new ones. Therefore, I highly recommend doing so with the help of this video. The video will also ask you to download and run a couple of programs for extra optimisations and other great clean-up features. This might sound sketchy to you, but I guarantee you that they cause no harm at all to your hardware. I have even bought the premium versions of these programs to get the best performance out of my computer. I could go one and explain everything; however, everything you need to know is in the video. Make sure to read the comment section if you need help, as it kind of serves for FAQ.
