Do you leave your computer on all the time?

When I get a new electronic device, I leave it on constantly for several days, this is called "burning in" time... if some weak part is going to fail, it will generally do it then, when under full 30 day warranty. Near the end of the warranty, I do the same thing... really put it through it's paces... leaving it on etc again, to make a weak part burn out before the end of the warranty. (But I always buy the extended warranties for electronics.)

Good wishes!
