One other thing to consider for the future is to use a surge protector if you aren't doing so already. I'd say this was essential if you are at a location where the power fails from time to time for whatever reason. Often problems happen when the power comes back on, as you can get a massive spike at this point. In my time I have seen one or two PCs that have been completely fried due to a power spike.

Surge protectors are not expensive, and over here you can pick them up in any hardware/electrical store.
They usually work & look like a normal extension cable, so you just plug it into the wall socket, and then plug all your power connectors into the extension cable.
