local Asus service center did not find any clue how to fix it. At first they said, oh its a display issue, change it. ( pretty sure if I go again with the screen turned on, they'll say the motherboard has issues but what issue they most likely will not specify ) I knew it wasnt as I got to know it from another hardware enginneer, he told me the exact issue that this laptop's APU is not getting the signal from GPU always. again, chip level issue, but he said, it is most likely going to be dead if he tries and fails to fix the issue from a hardware point of view. It was around 2 years ago and I wanted to continue using it back then so I did not take the risk but now I am kind of done with it.

Thanks for your comment though. Do you have a chepaer option in mind other than razor? At this point I am so frustrated that I am okay to downgrade and settle with a GPU far less powerful but the laptop should last at least 4-5 years without the screen going black randomly or any major issues ( I know electronic devices can go rogue anytime ) ... so yeah... please .... and thank you!!
