I've been experiencing random shutdowns usually while playing a game. Osmos, Where's my Water, Shadowgun and now Dark Meadow. There is and audible click that comes from the speaker and my Prime dies. I have to reboot. I've not played many games since .21 update so I'm not sure if it's a software issue or not. Anyone else experienced this? I've done a reset using the reset switch and a cold boot by holding the power and volume buttons at the same time. My hope is the next update fixes this as I don't want to RMA.
