Not so many people are having this problem actually and I definitely won't be telling them your solution!!!
You can't change mysql to run on port 80!!!
I think you were reading some posts and got muddled up.
If this did solve your problem(temporarily I'm sure) then the problem is you already have another mysql installed.
Remove it and put wamps mysql back on port 3306.
Until your wamp icon is green, you still have problems
