basically says it all
tries to shut down for hours, until I manually shutdown
then on restart I get error on shutdown
any ideas?

Shutdown issues are generally caused by a program and/or process that is
refusing to exit gracefully. The program and/or process can be from
malware or can be legitimate (such as an invasive antivirus like Norton
or McAfee). If you are using a Norton or McAfee product, uninstall it
and replace with a better program such as NOD32, Kasperksy, or Avast
(free). The Windows Firewall is adequate for most people. With Vista,
shutdown issues can also be caused by old/poorly written drivers so make
sure all drivers are updated.

is there a way for me to figure out which program is making it hang?

Try to remember what you have installed both software and hardware recently that may have caused this.
Here are some possibilities:
