Hey HJLBX ^_^,
I would suggest you to take the laptop to the Service Centre. Kindly don't try to open the laptop yourself out of frustration :lol:. Recently, my dad (who also owns a Toshiba) had a problem in which his keyboard keys would stop randomly for some time and then start working again. He tried everything like you and in the end I suggested him have the laptop's keyboard replaced by the IT guys. The IT guys replaced the keyboard and voila the problem was solved. So, at this point I would suggest you to take to a Computer Shop nearby (
Only if your warranty is over! else go to Toshiba Service Centre) and see if they are able to replace the touchpad.
Also, please ensure that you have disabled the Edge Swipes feature by following this below guide -
How to disable Metro edge swipes and touch charm gestures for trackpads (touchpads) in Windows 8.1 and Windows 8 | Winaero
I also had such issues, when sometimes the mouse would freeze and after a while it would work and disabling the swipes cured my issue.
Also, are you able to use your Keyboard (Try pressing the START or Windows Key and see if the Start menu opens or not) when your mouse is frozen?
