My nintendo keeps freezing

You do not. I am sorry but you need to return this faulty Nintendo DS. Hopefully you still have a warranty on this product but if not take it back and report problems with this product
hope this helps good luck :D

you need to get a diffrent battary

This means that there is a connection fault between the screen and the motheroard which stop the information reaching the screen. May want to get a replacement.Hope this helps you. If it does could you please rate me.

Remove the cartridge and then blow in it to remove all the dust, this should make it start working again

its a processor fault I'm afraid - needs new motherboard :-(

Insert the game BEFORE you turn the DS on.

their are 3 solutions but i cant asure that it will work
1. maybe when they play ds games like pac n roll the ds cardejects for some reason so sulution 1 is put tape ontop of the ds gamecard slot while their playin a ds game
2 maybe when they play a gba game the game pak is being hit by their chests or bellies so the card is moving a bit and the game freezes so put a big distance between the ds and the chest or belly
3. dont wiggle the ds alot and do you drop it often because if it is dropt often the ds will freeze often

IF it freezes the instant the DS swiches on, then your Action Replay is Bricked.

Don't worry though, there is a way to Unbrick it. You'll need a flashcard and a pc with internet.

For tech support on the DS in game freeze you can try http://nintendo.com/consumer?index.jsp

I found this site especially helpful when my system froze.

Try turning the console off and wait for a few days, and turn it back on to try again.
