The op-amp may be blown, they are 12V max.
ATX supplies are not known for their smooth spike free output generally so some more protection may be in order
Your FlexMods should be arriving there shortly, if they haven't already. Sorry to hear about the trouble. The Lasorbs dont' protect against long-duration overcurrent, only fast voltage spikes so I wouldn't fault them immediately, if this is what occurred.
strange it seems the driver is working just fine.
drlava - thanks

Andy....remove the Lasorb from one of the diodes and tell me what it does....provided they are not in series...

If you have a gig on saturday it's time to get into action.
Do you already have spare 445nm diodes?
Did you already measured the current running trough your diodes?
things for the future:
- Run each diode on a separate driver, if one fails you still have one diode working, so the party is still on
- ditch the ATX PSU, they are not so clean as you think, a computer mobo does some extra filtering on board.
- get better drivers (already sorted with drlava; good)
Try to run one of those diodes..one driver...no Lasorb...shunt installed onto the diode leads befor soldering up. Then lets see....
