Hmmm...well, using older drivers didn't seem to work either.
There was something I also forgot to mention as well regarding my computer "freezing". For example, when I watch a video on Windows Media Player, and the computer appears to freeze (i.e. can't move mouse, looping sound), I can still usually access the Task Manager using alt-ctrl-del. I still can't move the mouse, but I can move through different tabs using the arrow keys. I guess this means my computer doesn't 100% "freeze". Could this fact mean something else is going on with my computer?
