Here's the link that you can try to resolve the issue provided by Toshiba

Just follow the steps and if it would not resolve the issue, you can try this
ClickStart, and then clickRun.
In theOpenbox, typeregedit, and then clickOK.
In the navigation pane, locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
In the right pane, clickUpperFilters.
NoteYou may also see an UpperFilters.bak registry entry. You do not have to remove that entry. ClickUpperFiltersonly. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 7.
On theEditmenu, clickDelete.
When you are prompted to confirm the deletion, clickYes.
In the right pane, clickLowerFilters.
NoteIf you do not see the LowerFilters registry entry, unfortunately this content cannot help you any further.
On theEditmenu, clickDelete.
When you are prompted to confirm the deletion, clickYes.
Exit Registry Editor.
Restart the computer.
NOTE IF IT WOULD NOT WORK WE NEED TO DO A REINSTALLATION OF THE WINDOWS USING THE HDD PARTITION OF TOSHIBA REMEMBER THAT ONCE WE DO THIS ALL OF THE FILES WOULD BE DELETED AND WHAT WOULD ONLY BE BACK ARE THE SOFTWARES THAT CAME WITH THE LAPTOP WHEN YOU BOUGHT IT.
