I put Just Dance 3 on my external hard drive, and loaded it with USB Loader GX. All games have been working fine on it previously. However, it will randomly freeze and give me a buzzing noise, making me restart the system by holding the power button. I updated my cIOS to IOSx Rev 21, as well as I am using the newest USB Loader GX (2.2 I believe). After updating the same thing is happening.
