How have your video game systems broken?

[Grandia]

I've owned a Wii, Gameboy, DS, 3DS, PS1, PS2, PS3, PSP, Vita, Xbox1, Xbox 360 and a Dreamcast

and out of all this consoles only my Dreamcast broke, he still starts regular but after 5 minutes the system reboots and than it works again for a few minutes than again reboot and this goes on.
