No display, with fan running at top speed

When I start or plug inthe laptop the lights turn on with no display. After that the CAPS and NUMS lock blinks exactly 5 time and then the fan runs at top speed. I have tried the bios reupdate, cleaned the rams and SSD. I even tried to change these and removed the cell on the mother board with 30 secs of pressing power button
