3 long beeps 4 short beeps

[Sean154]

When I turn on the device it immediately black screens and beep 3 times short and 4 times long for 5 cycles and after the 5 cycles it’s powers up to the error screen and says that a usb device is connected but there is nothing connected and is says keyboard error?.

I’ve searched it up and tried every possible solution I don’t understand and could really use some help🤗.

Hi:

According to the beep chart at the link below, there seems to be a temperature issue of some kind.
