I would put the card in another machine and verify if it's actually bad or 
not.  It's more likely that the motherboard bus chips overheated and went 
south before the SCSI card.  

The other suggestions on the list about cleaning the edge connector and  
reseating the card and what not are good ones..

once a card (or any not overly hot chip/card device) is adequately "burned 
in".. it usually has a longer lifespan than you (unless is has a lot of 
electrolytic caps that run  the risk of drying out and stopping).


Check it in another machine.. (as well as you cables, clean the connector, 
etc).
