My first suggestion, read THE DEAD PC on my Web Page.  

Second, by no power, do you mean that the POWER LED does not light?  
Maybe you just knocked the power connector loose on the motherboard.  
Make sure the RAM and all the cards are seated properly.  (All this with 
power off and you grounded, off course!)

If this does not help, disconnect ALL drives and reconnect the 5.25" as 
the A drive.  If the system boots normally, at least you've eliminated 
the the MB, RAM, VIDEO CARD, POWER SUPPLY as sources of trouble.

BTW, as far as I know, NO floppy drives made in the lst 3 years need 
jumpers to be set.  Everything is done in your system SETUP.  If you come 
across a drive that does has jumpers, don't fiddle with it, just replace it!
