Hello!
So, this happened to me in the last days:
Installed 344.11 drivers, played Shadow of Mordor with no problems for a few hours, then tabbed to the internet for some mins, heard the GPU fan stopping...
At this point, that sounded strange to me, and I tabbed back ingame. Boom! Pc restarts. Played again with no problems for some time.
The day after, while I was just browsing on facebook, I heard the GPU fan stopping again...
Tried to launch anything that could make the GPU work, and Boom! Pc restarts.
The morning after, my pc wasn't even booting.
I removed the GPU, and tried booying with my old one (HD 6950), everything seemed to work again.
At that point, I couldn't accept the death of my 2-months-old GPU and went for a last solution: I uninstalled every driver, reconnected my 770 and installed the 337.88 build.
Now it seems to work again, but I'm afraid of what happened, my pc not booting doesn't simply mean a drivers problem to me.
Hope you guys can help, today I heard again that the fan stopped, checked MSI Afterburner and it said the fan speed was still 38%, I didn't believe in that so I opened Rivatuner, and... The fan restarted, BUT as soon as I started a game, pc crashed...
I heard updating BIOS could help, but the program I got from ASUS website says "This patch does not support this card!"
Sorry for the wall of text, I really have no ideas but sending it back for RMA :(((

Update:
So, before i was going to bed, i heard again the fan stopping, launched a random game to see the result and obviously the pc crashed...
But this time it wont reboot again! I removed the gpu, still no boot.
So i reinstalled the previous psu, a low quality one, and the system started correctly (still without the 770, i dont think the psu could handle it)...
Can i assume it was just a psu problem now?
Thanks in advance!

What specs/components does your rig have? OS? :confused:

It's definitely strange that the GPU fan stops competely. Lowest speed level should be around 30%.

My system is:
Asrock z77 pro 3
i5 3570
8 gb ddr3 1600 ram
Cooler master G650M
Windows 7 ultimate 64bit

The fans do not exactly stop, they slow down a lot. After that, pc crash if gpu is involved

hmm...strange...:confused:....
The program from Asus you mentioned above was the Bios update found on the GTX 770 DCII OC page or the Asus GPU Tweak utility?
If it was from the GTX 770 DCII OC page, try installing GPU Tweak and update the bios from the settings menu. 😉
Sorry to ask this question but is the card properly seated in the PCIe-slot and all power connectors are connected?
Is the fan cable on the graphics card damaged? It could be a faulty fan too. :confused: So many possibilities :eek:

I didn't update the bios, it was already updated.
The card is correctly seated in the PCIe slot and all the connectors are where they should be...
In the end, I managed to actually see the fans while the "silence" occurs, and I have to say they still run correctly!
And by the way, i tried reconnecting the old PSU even with the 770 attached, and the pc started normally...
I really have no clue!

Really strange...maybe a sensor on the graphics card delivers incorrect values respectively is faulty...RMAing is a bad thing, but I think there's no other way...
