Video Problems

For some time now, the video on my computer has not functioned well.  I have had to reset and reboot the computer to watch videos.  It was getting old. Finally, that remedy did not work.  So, I checkout the troubleshooting link on You Tube. They directed me to the Toshiba website http://us.toshiba.com/computers/laptops, to download updates.  I did.  It was an hour and a half download, but it worked. So far.
