My 3DS will charge but won't turn on
So I was just in the home menu placing badge arcade badges when the 3ds froze up and then crashed
I wasn't too worried because it had been crashing alot lately but, when tried to turn it on the blue light glowed but the yellow on didn't and it didn't turn on
I tried getting a new battery but it didn't work the blue light and only the blue light turned on the screen didn't turn on I've tried blowing in the sd card slot
I NEED HELP PLEASE

Oh dear, please tell me you didn't just assume your crashing device "a lot lately" wasn't a sign of electronic death. In the future, please do not assume that your working device that is suddenly doing an unwanted action is nothing to be concerned about.
This is definitely a board repair issue from my knowledge of the limited information provided. You may need to open this device and/or find someone with some electronic background to check it for you.

I assumed It was just over heating or overcooling

@Marc8804 _ Yeah, I can understand that. But considering that these machines can be connected to a power supply and played all day (yes I have teenagers that do that LOL), it's likely a good sign of potential failing hardware. I'm quite sure this is not a power issue but a component issue based on your anecdotal information.
