Welcome to TSG damage9.
Are the programs you installed listed in Add/Remove?
It sounds like at least one of them is unable to complete its update of the registry and is failing to register a dll.
If you can unininstall them I would do that. You can also see what happens when you try "step by step" confirmation from the boot menu. This might help isolate the particular file or application which is hanging up. Tap f8 repeatedly when starting to get the boot menu.
