Dell Inspiron 7559 Won't Turn on but All the backlit keys and power button are on

Hi guys, 

So just the last day my Dell Inspiron 7559 has been having some issues. I've had it for a year now it was brand new and when it is shut down when you try to turn it back on again, the keyboard and power light turn on but nothing shows up on the screen. I don't know if it's booting or anything. I hold down the power button for a while and it turns off and then back on, eventually after like 15 tries of this and 10 mins it sometimes turns on.

I've updated all my drivers and everything per Dell Support site and ran a full systems check and was clear. 

I reset the laptop while also keeping my files. 

Reinstalled new Antivirus and the like programs to see if it could possibly be that. 


Windows 10 Home 64-bit (10.0 Build 16299)

Intel Core i5-6300HQ CPU @ 2.30GHz (4 CPUs)

8192MB RAM

DirectX 12

NVIDIA Geforce GTX 960M

Integrated RAMDAC 

Drivers: nvldumdx.dll,nvldumdx.dll,nvldumdx.dll,nvldumdx.dll Version:

Any help would be greatly appreciated thanks!
