Do i need a ground loop isolator

[MingLee420]

Ive been having issues with my headphone amp and pc making this screech of grainy/distorted noise and maybe a ground loop isolator would fix it?

 

This video is pretty close to what im hearing 

It comes every like 3-5 seconds and stops and sounds like this video but much more distorted

Doesn't sound like a ground loop to me. generally the kind of noise you're describing is caused by the gain being too high somewhere in the line which is bringing up the noise floor. ground loops sound much more electrical. Think like touching an exposed audio connector that is plugged into an amp/speaker, or sometimes like high pitched erratic squeals.

I tried lowering the windows vol to 50 and lower from 100 and seems to be still there although the knob on the amp was half way, when putting it down i dont think i hear it and when its basically 0 percent on the knob seems to have the same sound and half way is optimal for me so im not sure what to do

This sounds more like a broken ground connection. The easiest way to test this, is to wiggle a little on the cable and connectors and listen when the noise cuts out or changes.
