it finally became cold in miami, so when i awoke, my windows were all wet on the inside, could condensation have occured inside my computer? It is about 10 ft from the window and i am afraid to use it, so i am writing from a friends pc... thanks guys!
condensation on window = condensation in computer???

There is condensation on your windows because the glass is cold from it's exposure to the outside. So unless your computer makes up part of your exterior wall, there is nothing to worry about.
You could always install Linux just to be on the safe side!

sandorsky thanks,

I thought something along those lines too, with only whats touching the barrier between the room temperature and the cold outside (i.e. glass window)
but anymore replies would be appreciated! Just for peace of mind.
Thanks all!

no, because the air inside the computer will be around the same temperature as the air in the room. Only if either the air in the comp or the air in the room was below freezing should you worry
As long as it's warm on the inside of your house you pc will be fine, although it might be a good target for a thief being that close to the window, unless it;s upstairs, in which case the thief would need wings...bah, i'm an idiot
someone prove me wrong

Condensation occurs on objects when the temperature of that object is below the dewpoint of the water in the water / air mixture in the atmosphere. The dewpoint is the temperature (at a given pressure) at which the water in the air can no longer exist in a gas phase and changes into a liquid: i.e condenses. The dewpoint varies with water content of the air (humidity) and atmospheric pressure (lower pressure = lower dewpoint temperature).
As the coldest part of the room is most likely to be the glass in the window of the room (assuming its colder outside) then you would expect that liquid water will condense on the window panes before it condenses anywhere else in the room.
Assuming that the humidity of the room stays constant, if the temperature of the room were to drop further then the next objects that would show visible signs of water condensation would be those that are good thermal conductors, i.e give up their thermal energy to the surroundings very easily. These would be glass or metal objects for example.
In the situation of your PC, if the room were cold enough then condensation would appear on the outer metal casing initially, and yes the water in the water / air mixture inside the case would also condense onto the inside surfaces of the case preferentially (as opposed to the components on circuit boards, as glass fibre is not a good conductor of heat).
As there is very little air flow through the PC case when it's switched off we can assume that no further condensation will occur inside the case, and any humid air diffusing into the case will deposit water condensation onto the metal surfaces of the case / fan grill as it enters.
If the humidity of the room is very high then there is the risk of large amounts of condensation on the outside of the case forming large droplets that may enter the case by means of gravity, but if this were true then I would expect the entire room to be very damp indeed.
Conclusion: If there is no condensation on the outside of your case then I'd switch it on without worrying.
Sorry if that was a bit long winded... Yoshi.

I think the second link is more likely.
The object that will form condensation has to be significantly cooler than the surrounding air. If you piped the cold air directly onto your cpu, you would have to be concerned with condensation, but a computer in a cold room has no worry.
