Problems Overclocking my GALAXY 660?

So many months ago, I had tried to overclock my GALAXY GTX 660 GC card using the "Xtreme Tuner", and any time I bumped up the power target over 100, the Nvidia driver crashes. Games play fine when the power target is at 100. I suspected that it might be because it wasn't getting enough power so I just left it.

Just today, I got a Corsair CX750M and I figured that now I could overclock the graphics card a bit. Yet I still get the same problem of the driver crashing after playing a game for seconds. Looking at the temperature indicator, it's only at something like 54 degrees when it crashes.

What am I doing wrong? Is it a problem with hardware, or am I not overclocking correctly?

So I was able to play a stable game with power target and core voltage all the way up, but if I even try to bump up the clocks even a little bit, the driver crashes!
 
What is the card clocked at when you aren't overclocking it? Sounds like either you got a dud card or a card that has a super high base clock, GPU Boost is weird and clocks much higher than the manufacturer states it will, and 660's don't overclock very well anyway.

According to GPU-Z, the core clock is at 1006 MHz, the Memory is at 1502 MHz, and the Boost Clock is at 1072 MHz.

I bought this card a LONG time ago anyways! Oh well, it seems like an isolated problem, because I can't find many other similar issues around the internet.
