Nintendo DS Lite randomly freezes! Thread

Good day!

I have a Nintendo DS Lite that randomly freezes while playing it and pressing buttons and you need to restart it. It can even happen right away upon starting the console and pressing some buttons, so I don’t think it’s a matter of over-heating, but rather the button press on the PCB! I opened it up and visually I don’t see anything wrong, cracked, broken or burnt on the PCB and I also tried a different battery. What could be the cause and how could I fix it?

Thanks in advance!

-Open cover very carefully and that to pairs of four buttons rotate to left or right or for 180, and then close and return screws again. But is not bad idea to clean them with alcohol before. And I also hope is not power button in question, in that case you need to find alternate way to give life to our little guy(to start him).
