Pilot 53Someone has done a bit of research on the firmware of the FTW3 cards, apparently cards effected with the red LED of death have a signal from the mcu relating to improper voltage at the pcie connection. When the card sees this it prevents it from turning on. Hard to tell if the card messed the mobo causing this to happen by pulling more than spec voltage, or if something in the card itself fried causing the controller to see incorrect voltage.

bmgjetI posted a indepth write up on it here and how to fix it flashing a modifed version with all the checks bypassed, Since my mates card failed like that which has no warranty and wouldnt boot on his computer but ran on mine.Got approval from one of the mods to post it but it seems to have been deleted.They left the MCU flashing tool post in the PX1 thread tho lol.But really unless you have hardware modded your card and have no warranty your best to go though EVGA and try you luck getting a replacement card instead of bypassing saftey features.
