Why does my general frame rate slow down to 40fps randomly?

fps

This has been bugging me for a while. Every once in a while, I find my computer to be sort of laggy and I thought it was because it was busy or something. However, I recently noticed that it wasn't any performance issue...I thought my computer was laggy because the frame rate slowed from 75fps right down to ~40 fps and caused very visible tearing. This is not rare. It happens many, many times a day.

I have no idea what is happening...I have an AMD 5670 on Windows 7 32-bit by the way, and I've heard bad things about AMD's driver support. Could this be the problem?

P.S. The frame rate slowdown is not just for games (I rarely play games, and have not played games in the time since I noticed this problem), it seems it's an issue for the entirety of Windows. I first noticed the tearing when I was moving around tabs in Google Chrome.
