Is it possible to kill a card with a multi tester?

I was in the process of volt modding my vga, and while checking the impedance from FB pin to ground, misplaced the probes, using the + on ground and - on FB. Now the card is dead.

Of course the card was off the system and unpowered. I cant believe that meter's current can kill something.

What can be wrong? There's any way to know where's the problem?

did you scratch it or anything?

I'm very sure there's no phisical damage. Maybe it was a static discharge, but didnt feel something like that. I had already soldered a wire to the FB pin, so warranty is gone.

Warranty may not be gone depending on how much sodler you used. Can you post a pic?

Also, I find it hard to believe that the card died from that. You had it unplugged from the machine and was testing with your DMM right? The only thing I can think of would ESD or maybe the capacitors had not fully discharged on the card.
