Accusing the drivers of killing your card is like accusing a gun of murder. The responsibility falls to the person holding the gun.
Maybe you installed the drivers incorrectly (IE directly over top of the old drivers)
PSU failed causing a spike.
cold-solder crack
overheating
excessive dust
excessive moisture
failed components
bad memory
dead PCI-e slot
electrostatic discharge
bumps
chip creep
short circuit
or natural electronic device death....
My point is - there is MUCH more than a driver that can cause your card to die.
