When you installed Win 7, did you also updated your Video drivers to the latest version? I am almost sure you didn't but I am almost positive that Win 7 did and this may be causing you problems as well.
Go to device Manager and under Display Properties, tell me what you have.
Now, there is a saying that goes something like this... "if it ain't broken, don't fix it!" and since you got it working, I wouldn't change anything until you are done playing with it.
