Hi,
Yes I would return it to the factory specs as there has to be something wrong and most
likely something installed or an older driver. Return to factory specs and then check for
BIOS, low level chipset, and other major drivers.
Check with Toshiba Support, their on-line documentation and drivers, and ask in their forums
about known issues.
