I'm using a dvi-D cable thinking I may buy a display port cable instead for my 120hz monitor, been meaning to for a while now so it gives me an excuse to do it now. But what are the chances if the dvi D port is stuffed could the others be too?
Very annoying indeed! I have had that issue with 332 drivers, in one of my monitors, now with 335 its gone!

Both 780 GHZ and 780Ti GHZ are custom PCB's (almost the same PCB as a matter of fact discounting some extra capacitors) both have 8-phase synchronous buck converter NCP4208 plus an unidentified Richtek 2-phase analog PWM labelled 0T=FG V1D taking care of a stable current supply for the the memory!
RMA that card!

First the Fans are leaking lubricant, now a high pitched whine comes from the area that the video card is in that I originally thought it was from the mobo, but now im not so sure, also around the same time the whine starts, all of my usb devices start going nuts, i'm also noticing stutters in games that it didn't happen in before.
The sooner the faster you get the replacement and forget about those problems you didnt pay for and dont need the stress because of it!!!
That's what warranties are for!

Look down for coil whine!

Good luck with your RMA!
Coil whine then, read a quote from one of my articles:
"Coil whine is mechanical resonance of the coil with the frequency of the signal passing through it. Physically, a coil is just loops of wire, sometimes with a core other than air. If the frequency of the signal is in resonance with the physical wires of the coil, the coil may vibrate.
There are many electrical parts/circuits which can cause whining noises, so don't just assume you are hearing coils. Annoying buzzing/electrical sound(s) are unlikely to eminate from a coil - you have something else making noise. Whining is caused by a part (or parts) physically vibrating.
Unto itself, voltage is not going to cause a whining sound. Voltage is electrical potential (actually, EMF); current through a device is dependent on the voltage across it. With a GPU, changing the voltage changes the operating frequency of various components within the chip and through the VRM sections, however something is probably in resonance with the signal!
