I need help.

My Acer Predator Helios 300 is dead. I need a new motherboard, and when I went to the Jaipur service centre a few months ago they said it will cost me 1 lakh for the motherboard. I bought the fuckin laptop for 1 lakh 6 thousand. I need someone from Delhi to find me a new motherboard or even a second hand working one if that's possible. My specs were i7 10th gen with rtx 3060. Help if you can please. It's been six months. I need this laptop alive
