Hi,
First of all, if you've recently installed any virtual drive software ( an exmple of this is Daemon Tools ), temporarily uninstall it, restart the notebook and see if this has corrected the error.
If the above doesn't apply, try downloading and installing the free KLite codec pack on the following link.

When the installation has completed, restart the notebook and check again.
Let me know.
