It can be a little complicated, and dangerous, if you’re not careful.  We probably should be calling an expert, or at least doing some research.

Hm, if you’re talking about a desktop computer, I think that power supply is one of those things that most people replace on the advice of a professional, to avoid damaging something.  Is it possible to be a bit more specific about what kind of computer you have?
