he was a great asset to gaming over all. He were a great programmer. He probably made the launch of Pokemon to even come true, thanks to his custom compression for the games to fit on a gameboy cartridge.
Most likely its overheating, prob needs new thermal paste on cpu/ gpu. That stuff after years dries up become crusty n no longer works to transfer the heat.
@salazarcosplay When it shuts off on its own, does the power supply light show red or orange light? If its red, most likely bad power supply. Orange is normal off, green when powered on, red is a fault.
Even after turning on, then wait for it to power off on its own, then what color? If orange then normal. I'd start with repaste. Most likely just overheating.
