Windows 7: Video & Sound lags - seemingly random

Video & Sound lags - seemingly random

Let's start with my machine:

I just put this computer together over the last weekend.
It was seeming to run fine, until a bunch of windows updates came.
I uninstalled every windows update I could.

I have gone into the BIOS and selected to default settings.

This is driving me crazy! When I'm playing games (Legend of Grimrock, even) or watching netflix. The sound and mouse lag like a robotic stretching sound (think Neo in the Matrix after he eats the pill and starts screaming and it becomes digital sounding). Sometimes it becomes unbearable.

Any thoughts on how to further debug and/or fix this problem.

UPDATE: did a clean install of the newest nvidia drivers

UPDATE: came back and it is definitely still doing it. Mouse is choppy in motion. Sound still lagging at clips.

UPDATE: updated the drivers on my RAZER DEATHADDER to the latest version. Seems to still be acting up.

UPDATE: Ran the system on 2 of the 4 sticks of ram. Still did it. Ran it on the other 2 sticks of ram after that. Still did it.

UPDATE: Removed the graphics card and ran windows. Still did it.

UPDATE: did complete reinstall of windows. Still doing it. This is starting to get depressing.

UPDATE: description of the lag - when it happens, it will happen several times in a row, with about 1 second intervals between the spikes.

UPDATE: in describing the pattern of the lag, it will spike out
