Doesn't matter, you need to uninstall them (as opposed to disabling them) and remove any and all files added by mods for it to have any affect.
I install the high resolution texture pack (The free DLC). After that the problem started.
Due to its nature, it wouldn't be causing this.
Also, verify your files after uninstalling your mods to be safe and wipe your INI files in (My )Documents/(My )Games/Skyrim.
Also, please use a better font color (personally, I like the default) as yours blends very well with the default background and is very hard to see.
