Very unstable (Freezes with weird noise)

[kevincrans]

my 3DS sometimes freezes in various ways with strange sounds, no matter which custom firmware I install on top of it, during boot, entering sleep, playing open_agb_firm games, or while playing a 3DS game and now also opening settings while writing this very article.
I assume crashes are related to Luma3DS, so I don't post them here.
I have a new3DS, I use it for GBA games and RPG Maker FES development(has it's own crashes already)
