Cursor loading icon every 10 seconds

Hey guys, i just finished cleaning up my dad's laptop and its running alot better then before, but theres still this weird problem where the blue loading circle will appear next to the cursor when im not doing anything. This happens about every 5-10 seconds even if my cursor is on the desktop and im not doing anything. Also, when i went into task manager and tried to see what processes were running, the list kept changing as if something started to run and then stopped. Each time this happened the cursor loading icon would appear. How do i get this to stop?
