Extreme Memory Leak with Version 4.0+

I have used Dolphin for 3 months now. It started off working fine, when my friend showed me this awesome emulator and all it can do! How ever, when I was able to play, I had Windows 7 Professional 64-bit as my OS. Now I have Windows 8.1 Professional also, 64-bit. After my fresh OS install, I downloaded all of my necessary programs and files to enjoy my computer to it's fullest. When it came time again to play with my friend, using Dolphin, it didn't seem to work (versions 4.0-299+). I didn't think much about it and we tried version 3.5, it worked perfectly for me. Yesterday, I tried to use 4.0 again, even after trying fixes like running as administrator, changing to compatibility mode and fresh installs, it didn't seem to work.

Here is what happens when I run Dolphin 4.0-652(used for SSBM):
Opens up perfectly.
Config opens fine.
Graphics opens fine.
DSP opens fine.
GCPad and Wiimote controller configuration windows cause extreme memory leaks. When I look at my task manager, I see that Dolphin is taking up over 1000MB of RAM PER SECOND! If I don't stop it in time, it crashes my computer. This also happens when I even just start a game.

I have done all I can do to my knowledge, but I'd like some input on fixes or bypasses to this, honestly BIG problem.

More information: I play using an Xbox 360 controller and Wireless receiver.

EDIT: Revision where the issue started to happen. Also changed the revision number for Dolphin that I use for SSBM.
