i have never found a cheap way to do this...but you might be able to isolate 
the problem by finding someone, perhaps in a pc user group, that would let 
you install the card in another computer, to see if it still works - if there 
is a problem with the card, there is, of course, the problem of it causing a 
problem with another computer, but i have tried a lot of bad cards in other 
computers as a way to troubleshoot, and have yet to hurt another pc - 
course, now that i said that, i'll probably blow one through the roof tomorrow
:) good luck
