Lots of text, sorry and thank you in advance, I'm very exhausted.
I just did some upgrading for my Dell XPS 8300 a few days ago. I replaced my AMD 6450 with an MSI GTX 770 OC TF edition, and I also replaced my 460W Dell power supply with a Corsair AX 850. I have an i7 2600 @3.4ghz processor and 8 GBs of ram, and this is my MB: http://www.findlaptopdriver.com/specs-0y2mrg-dell/
I've been amazed at how extremely powerful and quiet this GPU has been until now (but I'm not certain this is a GPU problem). I was messing around with my sound settings and a program called Virtual Audio Cable to try and have MSI Afterburner capture World of Warcraft game-play and only capture the game's sounds, and not iTunes. 99% of the time I listen to music while playing, but I would like to only have game sound effects in the videos I record. I played around with all the MSI Afterburner video recording settings to try and fix this, but to no avail, so I was forced to outsource. This program Virtual Audio Cable creates virtual audio lines, which allowed me to separate WoW's audio feed and record just off the virtually created line. I was pretty disappointed with the audio lag though, but I'm getting off topic here.
Anyway, after messing with all this stuff for a couple hours I noticed my computer would start to have this low frequency hissing noise when I opened up a game. It happens INSTANTLY when I alt-tab into a game, even if it's just a menu screen, and does not go away until I alt-tab back to my desktop, Chrome, iTunes, etc. I don't remember exactly when the hissing started, as it is not audible over loudish music, but I know that it's not from my speakers. I looked in my case while alt-tabbing and it seemed like the fans weren't picking up speed or anything, MSI Afterburner confirms that for the GPU fans at least, and my case is kind of small so I can't really accurately tell where the sound is coming from. I tried disabling every audio line, including the virtual one, through control panel in case this is a static frequency issue or something, but that didn't work.
Back to hardware though, when I installed my PSU the cables were extremely bulky and long so I had to stuff them into the empty hard drive and dvd drive slots to avoid having them touch fans, etc. Not sure if this is relevant though since I haven't messed with the cables since. Another thing that I was worried about when I installed this new tech was the GTX 770's pin cables. It came with 2 small 8-pin power cables that would not reach my PSU, and has 2 8 pin slots on the card, but when I looked into the cables there was only 7 out of 8 pins filled, so I just put one full 8 pin cable that came with my power supply into one slot on the card, and a 6 pin one into the other. Could this be causing any problems? Or is this hissing from the virtual audio line I created? Or possibly a PSU problem? I have noticed that my CPU and GPU temps have been pretty good while gaming, but my PSU seems hot as hell. Again, sorry for all this rambling, but any help would be greatly appreciated. I don't want my investment to fail so soon because I did something wrong.

I am 99% sure it's the GPU and 90% sure it's not a fan problem. I'm really god damn confused though, I just started up Trials Evolution, a game I could not play with my old video card, ran through some graphicly intense tracks, and absolutely NO sound. Then I start up WoW and even in basic menus with GPU usage at 0% I am getting the sound, this is also the case with Borderlands 2. And in both games the sound goes away INSTANTLY when I minimize or there's a loading screen. What the hell is this.
