Rzbox don't work

hi i have a chuwi rxbox. Today while I was using the pc it suddenly shut down. both the pc and the power supply were very hot, I waited for them to cool down and now it doesn’t turn on anymore. the power supply has the green LED on, but as I connect it to the computer, the LED goes off and I can’t turn it on? solutions? do you know what could be the problem?

check in this forum, some rxbox from amazon do not have properly connected inside fans and heat. is easy to connect
