Adobe Premiere Pro playback freezing and menus lagging on brand new laptop (help!)

I have recently purchased a brand new Inspiron 7506 2n1 from Dell, which was suggested to me for video editing. When I go to play back my footage, it is unable to and freezes as a still on the clip I am trying to play. I have tried uninstalling and reinstalling the software, and I have tried all of the suggestions that i've found online, such as the preference settings, sequence settings and so on. I am pretty stumpted by this and can't work out why this is not working 😕😕 if anyone could help that would be greatly appreciated! Thanks!
