Cpu usage spikes

Hi, I'm using a 2500k i5 and it very recently started having as the title random cpu usage spikes. When I'm moving a window or holding in a button or even launching task manager. Something like that but idk what to do there is no malware in question cause I've done a fair share of scans oh yeah and when I get the spikes the audio destorts for a short moment.
