Will freezing temperatures hurt my computer ?

It is true keep LCD screens in above freezing temps. Everything else is good to go in freezing temps, but some precautions.

Make sure the moisture level is kept at a minimum to keep components from rusting.

Make sure before you turn them on they are at room temperature. You may want to open them up while the thaw in order for them to dry out as they thaw.

I have an older book on repairing and upgrading PCs. ( not a casual one, one of those 16 inch door stoppers with every detail of every major part when it came out.) It made a point of not running a hard drive for a number of house after it was brought in from a cold climate because of condensation in the drive. It had a chart for number of hours to wait depending on temperatures, before and after. Apparently lots of people fry their lap lops by leaving them in the car overnight in the winter and then trying to use them in the morning. Other than running them before the warm up and drying period, you would be fine.

I would be careful of rodents, if you have an open slot on your computer you may find a mouse nest in it come spring.

If any elctronic items are stored in air-tight sealed plastic bags, they can be stored in freezing temperatures. Before use you should bring them to normal temperature.

Your only concern would be condensation building up on the components after bringing them inside. As long as you dont turn it on until its dry (If condensation appears) the components should be fine.

no cold won't hurt your computer.don't worry cold is good for it.
