This is something most of you are probably aware of, but once in a while we get a call to repair a dead computer which resides either in a garage or other very hot room. The usual cause is a dead power supply or worse a dead motherboard most likely brought about by extreme heat exposure. Here in Southern California in the summers temperatures can easily go up to 110 degrees or more in a garage and other rooms without air conditioning. This is a very hostile environment for computers.
Please try to keep your computers cool, they will appreciate it and will last a lot longer.
