Dell :: Lagging Cursor

Out of no where, my cursor has started to lag. For example, if I move it quickly around in a circle, it will move, pause for a second, then sort of appear where it would be had it not lagged.

It does so on a very specific interval, like when spinning in a circle it will stop momentarily every 2 seconds. I've also noticed while playing a 3D game, the graphics will lag slightly every 2 seconds.

I've done in-depth virus/spyware checks, defrag etc. It really just randomly started. It does it with my wireless mouse and the touchpad.
