Greetings.

Short of 2 months ago, I got myself a new Gigabyte GTX 760 which started out working just lovely. However, a few days ago, extreme graphical issues in basically every game emerged.

Attached is a short video of the issue in action: YouTube link

No overclocking performed on the card whatsoever, and I'm hardly running any heavy games right now. Card peaking at 63C according to GPU-Z with fans running at 46% when the artifacts are showing, so I'd doubt its a overheating problem.

I've tried the usual stuff, reinstalling the graphics drivers, completely dusted out the case, etc. I'm also always wearing an ESD bracelet when poking at/replacing any component.

The card should still have a warranty but I'd like to know what my options are before sending it away for an eternity to have it checked. What would be the most probable cause for this?

Misc. specs:
Intel Core i5-3570K
16 GB RAM
Corsair TX 750W
Windows 7 Ultimate

Sorry for my terrible delay. Anyway, I've looked into the GPU load but I couldn't really record it properly, so here's a small log file instead. Whenever it drops to 0 is when I tab out.

Strangely enough, the artifacts tends to come and go every few minutes, hence something feels periodically unstable. They also emerge 100% of every time I tab in and out of a game. From what I see when comparing the numbers to what I see on the screen, the GPU load without artifacts is averaging out at roughly 50%, while with artifacts it sits at 33-40%. Could this imply anything?

Similarly, the GPU core clock is fixed at 1084.4 MHz whenever there's artifacts present, while at any other value it works as it should.

Also, to be perfectly honest, I've never done any clocking in my life so I'd have to look into it a bit first should some underclocking be required.


EDIT: attached is a screencap of GPU-Z, clearly showing when the artifacts emerge as indicated by the sudden peaks.

Looking into the specs. of the card, I noticed that the factory default clock speed is 1085 MHz (base), which corresponds to whenever the artifacts emerge. Now why would it peak out like this even when idling at desktop?

Also:
Gigabyte’s GTX 760 WindForce OC 2GB graphics card already comes with a 10.3% GPU core overclock and 11.3% GPU boost overclock right out of the box.

You can download this: http://event.msi.com/vga/afterburner/download.htm and try underclocking. It's very simple to use, but don't like set it to 0 lol just slowly back down the clock a little at a time (3-5%) and try it. If it is artifacting at that specific clock speed, I'm led to believe it just can't handle that speed. Which, if it hasn't been OC'ed by you, is just a bad card.

How old is it? Might be able to RMA it.
