I have had to re-install my windows 7 home after it froze up on me several times. I then changed to windows 7 ultimate but still have the same problem minus the freezing. "NO AUDIO OUTPUT DEVICE INSTALLED" I have done all that I can think of including re-installing drivers checking with tech reports from others and so on all I find is for vista or XP. In the device manager I have an exclamation point on "HIGH DEFINITION AUDIO CONTROLLER" and the red X on the speaker symbol in the system tray. I've tried everything I can find to no avail. Is there anyone who can help??? Also my USB ports no longer work as well.
My Toshiba is model L505D-LS5007
