laptop stutters every 2 seconds

[Edu2k]

my dell inspiron 3451 stutters exactly every 2 seconds, my gpu usage is around 30% and ram around 40%, but sometimes they both go to 99%. the computer has a windows 8 sticker but its using windows 10 currently, maybe thats the problem

NO , thats not the problem. Then my laptop has xp sticker but i use windows 10 in best performance.
you have to reinstall windows 10 or roll back to windows 8
