Problem with JAWS

Dear friends,

Sorry for crossposting but I am having a queer problem.  Sometimes as I am busy 
working with JAWS it starts continous speech like r-r-r-r-r-r-r-r- and 
continues till I shut the machine or it automatically restarts.  I have Acer 
with realtech soundcard and genuine windows and office.  Please help.Thank you.
