Lenovo 700-11isk disabled graphics now the screen is black?

I disabled the graphics in the bios, bc the screen randomly goes black on windows 10, and after pressing power for 5 secs it comes back on… Or hard resetting… Irritating, so following a youtuber using a diff cpu, i disabled the graphics setting… His restarted, no problems… Mines restarted with a black screen… Any DIY steps to fix, or to the repair shop it has to go?
