jumpy scroll wheel

I have a Razor Deathadder essential mouse which I got around September and for the past couple months the scroll wheel has deteriorated in function, getting more inaccurate and jumpy over time. Randomly scrolling down a couple ticks when I scroll up and vise versa. I find this issue strange because the mouse shouldn't be dirty, I plugged it into an alternate USB port and it pretty much fixed the issue but only for a couple days in which it deteriorated again much quicker. Ive tried reinstalling the driver but it did nothing. New USB ports no longer do anything. Its really annoying.
