I have never re-stringed my guitar before. The other day I went out, bought some strings and started to attempt to re-string it. I thought I had did a good job, all the strigs were in nicely, but theres one problem. Now when I pluck any one of the strings it makes a horrible vibrating noise towards to top of the neck. It sounds like it's coming from the tuning holes, but I can't really tell. If any of you guys have some tips, it would be greatly aprecaited.

Maybe the tuner's loose?

Just tighten it with a small screwdriver or allen key.
By "Tuner" do you mean the knobs that you turn to tune it? or the hole you put the string through?
