as far as i can see there is no visible damage.
i did a jonny english cable sleeving mod, and along with the sleeving i got some ez-grip molex connectors(forget the brand). when i went to plug em in, they wouldnt fit into the slot on my card. by now it was 3 am with class at 8, so i quickly swapped it back to a normal molex. plugged my
pc in the next day, it went nuts, after some fiddling with the different connectors i narowed it down to the connector i switched back, and thats when i noticed id put the wires in reverse order.
a new thought: maybe it overheated when i first turned my
pc on and got heat damage?
