Question about PC Desktops
The power supply normally has a fuse inside. It sounds like this may have blown.
The power supply is one of those areas that are marked as "No user serviceable parts inside" This is because there are rather large capacitors in there and you can still get a shock even when the power is turned off. So I wouldn't try opening the power supply if I was you.
You could check all the power connections inside the box are still good after your dust removal expedition. Depending on your expertise you could check the output voltage with a volt meter. I think these are only 5v and 12v so no big danger.
If the power supply is faulty You can probably pick up a new one cheaper than getting your existing one repaired. Most PC shops would stock them. Just take your old one in with you so you know what shape / size to get.
