Yesterday night, I went on ahead to turn on my recently purchased DSi and for some reason the screen would flash white for half a second and shut off automatically. I removed the flashcard from the system and the problem still occurred. Seeing as how the DSi didn't even reach the main warning screen I considered the system faulty, and immediately filed for a replacement at amazon.com. Anyways, this morning I tried again... and amazingly the system is working fine now. The curious thing is that I had left the system without the flashcard on for the whole night, and when I placed the Acekard2i back in I experienced game freezes, which were quickly resolved by cleaning both the cartridge port on the DSi and the gold pins on the card. Is it possible that what I experienced last night was caused by a defect on the card, the input pins, or even a series of bad events? Just wondering if this has occurred to anyone else?
