If you’re wondering what the source of your computer problem is then you’ll have to do a bit of research to try to find the answer.  Google any error messages and see what people have done to solve the issue.  You can also try an antispyware software program.  If you’re running Windows Vista you’ll have to ensure that you’re getting software that is suitable for the operating system.  If you want the best Vista registry cleaner then I suggest looking into the RegCure program published by ParetoLogic software.  RegCure is easy to use and simple, just ensure that you’ve made the proper backups first.
