Asus Zenbook ux21e dh72 doesn't show any thing

Hi
Yesterday the laptop shown a blue screen error while I was using it as usual. but the blue screen quickly disappeared and I couldn't read the error type and then immediately rebooted in to the BIOS. So I left the BIOS with "save and exit" command. after that the unit remain still turned on but doesn't show any thing (not even backlit) the LED on power button and fan was on and device got warm like always. I turned it off by holding power button for 5 seconds and turned it on again but the same situation happened: LED on power button and fan was on. I attached the notebook to a monitor using HDMI cable but it doesn't sent any signal. I tried to drain the battery fully in order to make the device to reset the BIOS settings but it doesn't make any changes. also I tried to boot it using bootable windows flash drive but the screen didn't show even the Asus logo or anything else.
the OS is Windows 8.1. I have to mention that some blue screen errors were happened one month ago but it was solved till yesterday. for example the error messages was:
IRQL_NOT_LESS_OR_EQUAL
KMODE_EXCEPTION_NOT_HANDLED
It doesn't show any reflection to any button at the startup (Like F2, F9, F10 or delete) at all.
any help would be appreciated.

 

It could be any number of things

Bad motherboard
Bad RAM
Bad display adapter (primary GPU)

You can try replacing the RAM and resetting the BIOS via removing the CMOS battery for 15 - 20 minutes. There's a fair chance something will need serviced or replaced, though.
