"About a month after I started playing Castlevania: Dawn of Sorrow, I would press the jump button (B) and occasionally the DS would simply turn off. This happened randomly, but I had no idea what it was due to.

I went to the repair center and they told me it was because the mainboard was fractured right around the B button, but it was under warranty, and they would replace it free of charge. I asked the guy if they ever encountered something similar, and he replied in the negative.

I guess I just have to watch the amount of force I use when pressing buttons on the DS! "

yes. nintendo does have spaz out warranty.

i cant really talk considering ive hit many things(ceiling fan,tables,people...) with the wii-mote bowling and playing baseball, wii sports style!!!...

holy crap, how hard are you hitting those buttons? my DS has that cracked left hinge that was in the news a while ago and then disappeared. I can't find the reciept to get it fixed...
