A lot of manufacturers sell overclocked items, they just need to make sure they're stable before mass producing them. Bottom line is any item can fail.
As far as "turning off Overclocking"... if the card came overclocked, that is the "default" condition the card is intended to operate at. Thus turning off the overclocked condition (lowering the clock speeds) would "technically" be running counter to what the manufacturer intended, and could "technically" void the warranty.
I’ve had a non-overclocked card overheat and go bad on me, thus my experience with the display driver stopped responding issue.
It happens.
I would suggest you call the manufacturer, tell them your situation, and see about getting a replacement card.
My two cents.
