I am trying to fix my son's laptop, which has no sound. It is a Toshiba laptop running Windows 7.
First, I should explain that there are some other problems. The laptop sometimes freezes on a start or restart. We have to just shut it down and then on restart, we get a message that the system had been unable to start and gives us the option of starting normally or performing a startup repair. We opt for the latter.
I ran Malwarebytes and found some crap on the computer (i.e. Bandoo toobars and other junk). I quarantined the thousand + of those things, but it still has that restart problem. It's not every time, but often enough.
As for the sound, I uninstalled the sound output device numerous times. I may be reinstalling the wrong one since I'm not positive what the laptop has on it. I believe it's real tech high definition audio controller.
In any case, when I install it, it doesn't actually install. I find that "no output audio device is installed." In an online search, I found this to be a common problem with Toshiba laptops. I also found that the USB ports don't work, which I discovered seems to be part of this problem.
Anyone know where I can start now with this?
Edit: My post was moved to this forum, although I don't believe the problem is due to a virus. As I said, I did a search online and found that this problem seems to be a common one with Toshibas and is also related to USB problems. The USB port on the laptop is also not being recognized. I added the information about the virus scan in case someone thought the problem was due to a virus - to let them know I already scanned for viruses as part of my problem solving attempts.
Now I have no responses at all to my post. I don't know what else to say about the problem or which forum is best for my question.
