I have the model with Intel Core i7-7700HQ @ 2.80GHz and Nvidia Geforce GTX 1050 (2gb vram) , 
A while ago I contacted a laptop tweak service and they undervolted my laptop to -250mv. At first it was working fine but I thought I should reset it anyways as I wasn't comfortable with it. Soon my laptop started randomly shutting down and now recently random glitch lines have started appearing. Once these lines appear the laptop crashes. How do i fix it? I have reset the laptop, reset bios, reset voltages. help!
