GPU giving BSOD after forced shutdown

Hello! I think I just killed my GPU but I'm not absolutely certain. I'm hoping maybe you guys could help me determine if this is more of a software issue then dead hardware. Firstly the shutdown is because I keep putting my fan speeds too low while gaming, causing it to overheat and forcibly shutdown.

The only thing I've tried so far is reinstalling the display drivers from safe mode to no avail. Once installation is done and I restart I'm able to reach the welcome screen. However the screen flickers and shows faint, black scattered lines, then it continues to desktop where it flickers more, is darkened, unresponsive and has missing icons/graphics. This is shortly followed by a BSOD.

Is the graphics card dead? Or could this possibly be something else? Here's the report from BlueScreen viewer. If there's anymore information I can provide let me know.

Specs

i5-2500k @ 4.3ghz
Sapphire 7970 3GB
ASUS P8Z68 DELUXE/GEN3
Corsair HX850 PSU
G.skill 8gb DDR3 1600
Crucial M4 256GB SSD

Looks like your graphics card has reached the end of it's life.

Why?

You've likely killed it.

When one has the ability to cool overheating hardware and doesn't use that ability, leaves me in a state of confusion.

I agree with Mellon Head. You probable cooked your video card and maybe more.
