Hi, and welcome to the Forum, I guess you are a Newbie here because you have shown your email address - NOT a good idea to ever show this on-line. If you want members to contact you privately then you can invite them to use your Yellow Envelope; though normally all questions and answers should go through the Helproom. Also you can download the PDF Forum Guide which you will find on the main Helproom page - on the right-hand side near the top.
Now to your question ....
If this has only recently happened, try a System Restore back to before you had the problem.
or ... Run CCleaner from click here this fixes many things.
