[G750JX] Laptop Screen Turns On Only After Booting Into Windows

[P3rk3l3]

Hello,

My laptop's ( G750JX ) screen doesn't turn on during boot, can't enter bios at all or see the boot logo, but once I get into windows it turns on sometimes. I managed to get into bios on a secondary display to restore defaults, and also tried re-flashing the latest bios using a usb stick but no result.

Sometimes the screen doesn't even turn on even after booting into windows unless I reinstall the nVidia drivers.

Does anyone have any ideea about what is going on or how I could fix this ?

Thank You !

If it is only working sometimes, and it works fine, without any incident, on an external monitor, then I would say your graphics card/GPU is probably on its way out. If that is the case, you will need to have it replaced (or replace it yourself), which actually may require the motherboard be replaced as well.

NOTE: If the laptop is under warranty, contact the manufacturer about a repair or replacement.
