lagg Unsolvable PC lag and Stuttering, Please Help

[ankit_sangeet]

I am from India, and i have a fairly average pc buildSpecs:-

CPU - i5 7400

GPU - MSI GTX 1060 3GB OC edition

Ram - Gskill Ripjaws 2400mhz 2 x 8GB sticks

Motherboard - Gigabyte B250m

PSU - Cooler master 500 watt lite

Storage - 480gb SSD. 1TB 7200 rpm HHD

 

My issue is, every component is working fine in my knowledge, everything from temperatures to thermal paste to Cpu cores are working fine, but still i find frame drops in my day to day functioning, like the videos are laggy, the green progress bars are stuttering and even i am facing way more less FPS than i used to get. Even the loading circle in the chrome browser tab is stuttering.

Also i have a weird constant static noise in my USB Speakers
