did i break my gpu?

my system: i7 4790k 8gb ram, 850watt PSU, PNY GTX980 Ti

I built a nice little water cooled mini-itx gaming PC, everything fitted in a corsair 250d case. Only thing that bothered me was the gpu had a reference cooler, and it sounded like a jet fighter taking off when I overclock to give myself some FPS headroom on BF4. without OC, 1440p Ultra, bf4 sometimes drops below 60fps when there's a shit ton of stuff happening, with OC, BF4 never dips below 75FPS, and averages around 90-100FPS

anyways, i had my GPU overclocked to 1440mhz, +87mv, and at 100 percent gpu usage, it was at 110 percent TDP, and stayed at 70 degrees. It ran BF4 and Witcher 3 for hours and hours and hours without a single hiccup. But it sounded like a jet roaring in my bedroom.

I ordered a Arctic hybrid II, and I installed it onto my GPU today. After the nightmare that is getting it to fit inside my case because arctic wanted to be special and have rear mounted radiators, I opened up BF4.

I kept a check on temperature, and it plateaued at 70 degrees after 5 minutes. the only difference is that it wouldn't go past 1330mhz. And then everything went black. Monitors had no signal.

This, of course, is nothing new to me. Previously, I was running SLI 660TI by MSI, also overclocked. the worst that happened was artifacts started to appear, and NVIDIA drivers shut itself off, reporting a kernal error, but it always restarted. This time, it was not the case.

I entered the windows 7 boot screen, and it froze, displayed some artifacts, and dropped me down to the lowest resolution. I logged into the desktop, started up GeForce experience, and it told me to download new drivers. I installed "new" drivers, and I rebooted. Same issue. went back into GeForce, and again, it told me to install new drivers. And I rebooted again, and the same thing.

I checked GPU-Z, and while it detects the GPU, it read 0mhz on the core clock and memory clock. Everything behaves exactly as it behaved when I just installed the OS, but before I installed drivers for the first time.

I checked device manager, and it gave me error readings on the 980 TI, saying something like "windows disabled driver because device reported error"


What do internet?
 
You most likely fried it. Try it in another computer but I bet its fried. Probably done something to it putting the cooler on.
 
but there's no sign of damage. i checked the solder joints, and they all appear fine. There's no external sign of damage. don't gpu's usually fail more spectacularly? like smoke or something?

it seems unlikely that my gpu just quit after installing a liquid cooling system

Not necessarily. You could have gotten it with a charge of static electricity. Like I said, try it in a different system and see what happens. If it don't work there, then you fried it.
