My old acer aspire v3 571 g laptop showing no bootable device in a blue box screen

goodboy

When i restarted the pc after a fan cleanup of my own it turned on well and it was cooling so well but after some days when i turned it on my laptop showing no bootable device hit any key in a blue box
so the biggest issue is that the pc screen broke one day after that and cant see anything. When my laptop boots up it usually blinks an orange light of hdd near the sd card reader but when i turns on it shows blue light for a second and goes and no light later.Please help when i connected the laptop with a monitor nothing is showing and my screen i broken im stuck pls help I love this laptop and has been using it for over 7 years its performance is still butter smooth in windows 10 pls help

The first issue, the intermittent HDD boot error suggests either its connection to the mainboard needs to be re-seated a few times to clean its contacts OR it is starting to fail.

The second issue, the broken screen and no external monitor signal, suggests that the mainboard has been damaged. Did the screen break from a fall onto a hard surface?

@JackE
when i tried to re seat some times the hdd light turns on continously but blue colored light

and the screen broke not due to falling but my brother by mistake sat on the screen when it was operating 

thank you for your response

You can try to turn the external monitor or TV on by pressing FN+F5 combination. If still no external output then it's likely that the mainboard has also been damaged when your brother sat on it.
