System Testing doesn't work, as well audio, recording and DVD player.

[Cabeça de Vento]

MY OS is Ubuntu 14.04LTS and I have a HP Pavilion dv6500. Everytime I launch System Testing, it breaks after a hour of use (I cannot precise in which test it breaks), it restarts my pc and when I relaunch it, it asks me if I want to continue with the last test that remained unfinished. I click Yes but the program stays unresponsive for hours, until I finally quit it. Then, when I open it again, it welcomes me, but it stays stuck with a white window and the OK button (incomplete Suite Selection). Doesn't work either.

Any suggestions?

There are some things in my pc that aren't working, like audio and recording, as well DVD reproduction, and I thought that testing the system might solve it since it as a connection with software updater and launchpad (I guess). But it isn't working!!!

Closing, this is no longer in scope (as checkbox has been removed from Ubuntu installs)
