Is my mobo defective or my gpu?

ok that was too advanced for my puny brain to comprehend... would you mind putting that in lame mans terms? lol

EMI=electro magnetic interference.

ok, is there anything i can do to confirm or fix this?

I'm not sure, can you make a recording of the sound? maybe with a camera and upload to youtube?

So after a day or so of running the computer it started to do the same thing with the sound... my monitor has built in speakers, if i connect with the hdmi the sound cuts out every 5 or 10 seconds for a couple seconds. If i connect with the onboard sound there is static at all times although the more load is on the gpu the louder the static gets... if i'm just working in windows i can barely hear it, but if i game it gets ridiculously loud. the more intense the graphics the louder it is. some games its so loud that i cant even hear the sound from the game lol.
anyway I've tried to reinstall windows, install the drivers that came with the card and latest drivers and the whql drivers... i did notice that when the gpu driver isn't installed there is no static. lol just now noticed that there is static when i scroll on a white page... weird...

lol whitelotus... i totally get you... i am so sick of this i am starting to wish that i had never built this system... the problem i'm having now is CONSTANT whining sound from the computer. Not sure if its the gpu or psu or mobo but the noise is from the hardware... and if i run an intense enough game the whine does come out the speakers.

Which one of these two issues are you having? The second one sounds like Coil Whine. I'm not sure there's anything you can do. You might be able to RMA the card for a replacement if it's coil whine.

Well I would like to suggest a different gpu that isn't a reference 660 so a 660 twinfrozr ii or a 660 dcuii top or if you want an upgrade get a 7870. AMD VRMs are reasonably high quality Nvidia gtx 600 series VRMs are if at best. The other option is to cover the sound section of the motherboard in some kind of metal that is grounded o the case or a grounding line on the PSU cables.

Silkstone, the first issue was with a hd7770 card i rma'd that and got a replacement when that had the same issue, asus said that the card wasn't compatible with the motherboard so i got the gtx660. considering I've tried 3 different cards and the problem has been there with every one I'm fairly convinced that it isn't the card.... the only difference with the gtx card is that it doesn't bleed to the speakers unless its heavy graphics where with the amd it bled to the speakers no matter what i was doing. Now its just the sound from the hardware... although i just stuck my head in the case while a game was running and it seems like the gpu is whining a little but it also seems like the psu is whining a lot louder than the gpu... hard to tell when its so close to each other... guess I'll take it out of the case and lay it all out on the floor and run it that way. too tired to do it today though maybe I'll do it tomorrow night.

Ok if all your gpus did it then the only possible culprits are the PSU or MB. Try a different PSU as I really doubt that the issue is motherboard side as those barely ever have issues with coil whine these days also because I think the cx 750 PSU use a platform that is at it's limit resulting in coil whine and EMI.

i did try another psu... same problem... this is why I'm ready to rip my hair out... the only thing that i haven't tried a different one of is the cpu and hard drives and i seriously doubt that its one of those.
