I have a Toshiba c55-b series Laptop I bought in January 2016, 3 weeks ago its Windows 8.1 OS malfunctioned and I had to do a reset of it. It was only a temporary fix since the system went from being fairly fast to slower than a snail. I got off what files I could and did a full recovery, but even though it is supposedly back to "factory settings" is is very sluggish now. This is unacceptable but the unit is no longer under warrenty. Anyone have any advice what to try next. This unit is used by my daughter for nursing school and this slow speed is not going to work.
