Hi Galway girl,
You still have not provided the info requested (especially the One for Nunz report of your installation), but you have made a start.
I suggest you move the lyrics plug-in (gen.lyrics-ie.dll) out of the Winamp/Plugins folder to some other location and see if Winamp works. That plug-in (from 2001) is probably not compatible with Windows 7. If it is that plug-in that's causing your problem, you will need to get a compatible update from the person who made the plug-in or look for an alternative if you still need what that plug-in provides.
If it is not that plug-in causing the problem, please provide the One for Nunz report.
"In most if not all cases, also providing a list of all plugins installed can help us to diagnose many problems.
You can use DrO's One for Nunz plugin (gen_nunzio.dll) to produce a list of all (1st & 3rd party) plugins installed.
Install the plugin, open Winamp,
Go to: Prefs (Ctrl+P) > Plugins > General Purpose > One For Nunz > Config,
Checkmark "Open text file once generated",
Click "Config" again,
Then click: "Generate all listings (as below)"
When Notepad opens, save the file (via: File menu -> Save As) and attach my_plugin_list.txt in the zip along with your HijackThis and dxdiag logs (if required)."
