Motherboard issues, how can I fix it?

[Lucascsiqueira]

Hi, 

I bought this laptop on 2018. It was working normally until a day it just started freezing the screen, displaying some different colors. I could not turn it off and after like 3 hours that it was frozen, it just shouted down. Now, I try to turn it on and the power light turns it on, it make a sound that looks like it is going to turn it on and shuts down. Then the power light keeps blinking. I went to a store in my city and they said it is the motherboard, that I would probably have to send to HP to fix it. I would like to know if you think it is actually the motherboard and how I can send to HP to fix it? 

Thank you, 

Lucas
