Well something is definitely shorting, I would not put any more fuses into the socket until you think that you may have fixed it (you may damage the ST more), I have also assumed that the correctly rated fuse is being used (it may be worth checking but DO NOT use a bigger one in).
I think that the fuse is mounted on the power supply, if so take the power unit completely out and then see if it is still blowing by putting a fuse in it (remember completely unplug it from the main board, and do not fry yourself). If the fuse still blows then the power supply is up the spout, you may be able to fix it but I can not help you there really (look for melted components, black connections to the PCB or melted solder). At a long shot (it is something that I would try but do not recommend it), if you are going to chuck the power supply away you could try putting a real big fuse in there and seeing what is getting hot (look for smoke and all that), e.g. if a resistor or capacitor just melts and falls out then it is most likely to be that. I DO NOT REALLY RECOMMEND THIS.
If the fuse works fine then just have a look around the main board to see if any thing is looking burnt or melted in any way, look for screws and connections plug half way in, any socketed chips could need a firm push back into their socket too. You could also try completely removing everything from the main board like floppy drive, keyboard, hard drives, cartages, etc (not chips) and seeing if the fuse still blows when you switch it on.
More than this and your best beat is to go out and buy another (unless someone knows were it can be fixed for cheap).
Does the fuse blow straight away?????
