Hello
Do you have the same problems with an external mouse or just the touchpad?
If an external mouse works properly you can use this one to make a recovery installation. This can help you to solve the problem if it’s just software based.
Last but not least did you already try updating the touchpad driver? You can find it on official Toshiba website:
