Precautionary Message

I'm having some problems with my computer, i.e. it's become very noisy after me moving it from study to kitchen (near aircon). It was never exactly quiet but not this bad. So, given that my comp meltdowns traditionally do happen on holidays, I'm posting this in case the comp crashes and I can't tell anyone! So if I'm meant to answer something, you know why it'll take a bit longer, i.e. till I can use the comp at the local library.

Sigh. So far so good but this noise isn't normal and I won't be able to get anybody to check it over until after New Year's, I shouldn't think.
