I have a Raspberry Pi model 2 B with Raspbian.
When I plug in the power source, only the Green LED blinks, no Red LED.
The OS successfully boots and I can use the Raspberry perfectly. As soon as the power supply is plugged in, the Broadcom chip gets very, very hot, very fast. It burns when touched.
After 2 minutes of usage, the RasPi unexpectedly shuts down and after 3 minutes starts up again. It then continues in this loop forever.
I have re-formatted the MicroSD card and re-installed Raspbian many times.
I have installed a heat-sink to the Broadcom chip, and have tried with 3 different power supplies, 2 different USBs connected to my MacBook Pro 2014, connected to a USB-wall charger, and tried with an old BlackBerry charger of 5V and 700mA.
What is going on?
Temperature measured with the command line function measured 90.7°C directly after booting.
