1. Canned air. (that's it, you tell me!)

Help, I have an Acer Aspire 5750Z-4835 which shuts off sometimes while I am working. I lose all data & get an error message & have to wait for files to reload, which is very discouraging.
It seems as though there is a short of some kind. The battery is charged & all I do is touch it and it will go off, taking my work along with it for good.
