Laptop black screen after changing settings in BIOS

[Blitzhartwright]

Laptop Model : Asus N46VZ
OS : Windows 10

what i change in BIOS settings are :

• ■ Launch CSM - Disabled
  ■Fastboot - Disabled
  ■Secure Boot - Disabled

after that, i press F10 to save changes and exit.
laptop will restart, but when restart i got black screen.
Keyboard light, Notification Light all lights up, Fan is running.

what is the possible cause ?
is it VGA ? or something else ?
how to fix this problem ?

thank you very much.

Hi,

Please do try these troubleshooting steps that may help.
- First is to do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If it will still load into a black screen, try connecting an external monitor and see if you'll get any display from it.
- If the screen is still black proceed with reseating the RAM's.
- Remove the RAM's off for a second then put them back in making sure everything is seated properly.
- If it will not work, I would suggest opening the laptop and reset BIOS by removing the CMOS battery for a second then put it back in.
- And if all these will not work that means that the problem may lie in the motherboard already.

If you can get to BIOS reset it to optimized defaults

Could be a number of things, have you tried plugging in an external monitor?
