Problem Restarting with Vista Home Basic x86

I am on Windows Vista Home Basic x86.
When I try to restart my computer, I get hung up on the "Shutting down..." screen and I have to turn my computer off by the case, which is very unhealthy. I think shutting down the computer works fine, just restarting is troublesome.

The only recent change to my computer is that I installed Sunbelt Personal Firewall. Could my Firewall be somehow blocking a process that lets the restart process go smoothly? I'd really like to fix this.

 

To determine if this is the problem, disconnect from the internet and uninstall the firewall. Then attempt a restart. If it works then you know it is the problem and you can find an alternative program. If not, then you know it is not the problem and we can assist you to troubleshoot further.
