I am at a complete loss with my Toshiba laptop. Neither the sound nor the USB ports are working. I have tried uninstalling and reinstalling drivers, but no success. Here are some messages I get:
High Definition Audio Controller has a driver problem
Hardware devices are not working and not detected in WIndows
Device Driver was not successfully installed [High Definition Audio Controller]
Your device class filter was not recognized and your device might not be recognized when you plug it into a USB port on your computer.
This problem may occur if upper and lower filters are used in the registry.
This problem may occur if upper and lower filters are used in the registry and are corrupted
The USB controller is in a failed state or is not currently installed. The USB Controller must be installed or in a working state for this trouble shooter to run.
Obviously, I have tried running various troubleshooters found on the Microsoft website and have attempted to reinstall drivers (after uninstalling them). I searched the internet high and low and tried every repair option I could find.
Does this mean there are hardware problems? Do I need something replaced in the laptop? New sound card? New USB ports? Should I just scrap the computer, sell it for parts? I don't want to waste any more time on a hopeless case.
