nVidia Drivers Crashing Periodically (GV-N670WF2-2GD)

[exp3000]

Hey Guys,
I have purchased the Gigabyte GTX670 (GV-N670WF2-2GD) about 2 months ago and it has been working without a glitch. However, recently my drivers began to crash periodically (every 5 minutes or so) and recover. I have tried installing new drivers, beta drivers, drivers provided in the gigabyte website and have gone as far as setting up a fresh install of windows 7 64bit. I’ve never overclocked my card but have tried to lower the clock speed to fix the problem, but did not have any luck.

Any help would be appreciated.

Motherboard: Asus P8Z68-V PRO GEN3
CPU:  Intel Core i5 2500K 3.30ghz.
Memory: 8gb oKingston (KHX1600C9D3
PSU: OCZGSX700
Windows Action Center provided me with the following:

It looks more and more like a hardware failure. I have similar problem with my GTX 650ti (GV-N65TOC-1GI) - purchased it 3 months ago and it worked like a charm the first few weeks. Then all of a sudden a black screen in DX10/11 game (BSOD with TDR 116 type error) becoming more frequent after that.
I'm considering RMA because I ran out of ideas - replaced the PSU with new Seasonic 620W; tested the RAM with memtest one stick at a time; got new hdd with fresh Windows install; tried downclocking the card (it's factory OCed); tried all drivers from 306 to 314 with no luck.

I'll be extremely happy if anyone from Gigabyte could shed light on this problem. It's definitely not an isolated one!

We both have exactly the same problem!
