OTOH, if you go to the mechanic don't be surprised if he's asked if you kept up with regular oil changes. Clearing temp files is basic machine hygiene/maintenance, just like keeping up on security patches is. It's not unreasonable to check those BEFORE looking for underlying problems.
(Just like if someone says "my machine won't turn on," you want to look at "is it plugged in" before anything else.)
