Why is my Chromebook so slow?

Episode 1489 (1:58:12)

Larry from Altadena, CA
Acer Chromebook

Larry has an Acer Chromebook that freezes up intermittently. Leo says that it may be a good idea to "Powerwash" it from time to time, but it's not a normal thing for the Chromebook to be doing. Powerwashing will completely reset his Chromebook, though, so he should make sure he's backed up.
