Hello I just bought a HP - ENVY 700 Desktop http://www.bestbuy.com/site/hp-envy-700-desktop-12gb-me...{adtype}:{network}&s_kwcid=PTC!pla!{keyword}!{matchtype}!{adwords_producttargetid}!{network}!{ifmobile:M}!{creative}&kpid=8997042&k_clickid=7bf2d0b4-1ecb-9869-5345-00004846fc60



and i put a gtx 660 sc into it. its pretty quite, until i load up a graphically intensive game such as bf3. I am SURE it is not coil while on my gpu or psu. it makes a hissing sound like blowing air through your teeth :(  help please!

I am sure the stock PSU is nowhere near powerful enough for a GTX660, considering it only came with integrated video. Assuming you haven't already killed it, you'll need a PSU upgrade for that card. On a budget, an Antec VP-450 would do, or a 450W Rosewill Capstone.

Well evrything runs fine and the psu is 460 watts so its more than what you suggested. the minimum for gtx 660 is 450W

If it makes that noise, you're probably boiling electrolyte, varnish, or otherwise overloading the PSU.
