gpu coil whine and flickering on screen?

I got a new asus gtx 970 and i noticed when playing world of warcraft it has some coil whine and horizontal lines flickering across the screen.
I have tried reinstalling drivers and i have vsync turned on so everything is set up to be at 60 fps which is what my monitor's refresh rate is.

realized my the coil whine was coming from my psu, getting better quality psu to fix the problem. Same with visual problem, im assuming its because iI need a better quality psu, going to try this before I try to replace the gpu.
