This doesn't sound like a software or driver issue although you could try downloading the latest driver from their website just in case.
Also try re-seating the card in case it is not quite fitted correctly.
Did you ensure that you were earthed before you worked on the card? Static electricity will destroy components on any electronic card.
You could inspect the card for damage, but as the legs on the chips are 0.2mm wide and the processor is probably a BGA with the connections underneath, I don't think there will be much you can do. Repair to these cards is a specialist job, it may be a better idea to write it off and buy a new one.
