Question computer stuttering for no reason when loading any game right after pc turn on or application closed

[voicingbutton]

my computer has started to act strange recently, it started with a few stutters but now its happening on a daily basis.

every time i turn on my computer my pc is laggy for a few seconds then it will stay laggy for a long time until i restart again then it isn't laggy but when i launch a game and I'm finished playing the game it starts to get stuttery again and will persist until i restart multiple times, and when I'm playing in game it feels like its running at 1fps and and if i tab out it will stay that way until i close the game and restart then it happens again.

i am looking for anyone who can help solve this issue or guide me to a solution

CPU- i7-8700k

GPU- msi rtx 3070 gaming x trio

maybe open taskmanager and check out the cpu,gpu,memory usage first , see if we can find something abnormal

have you ever tried cleanup your system and disk to get rid of some trash that could possibly slow your pc down
