Replaced motherboard 3 times already - Alienware x17

So I have been having problems lately with my laptop and the motherboard was replaced 3 or 4 times already. Last replacement was on 10 jan and was happy with support. But two days back I had problem in the morning when I tried to turn on laptop it stared blinking 3 red and 5 blue. But I quickly did something and it started working normal. 

Now today same thing but this time it's dead. I have my Thesis two weeks later and these people replacing motherboard again!. Is there a problem with X series laptops? Is it why they discontinued em?

What should I do in this case I can't wait for a motherboard replacement every month! Am am in EU how good is the customer service in EU🥲

Support refused to give me a permanent solution. Customer service said they will help me with a replacement. But when connected to technical service team they said there has to be an issue 3 or more times in a month to do so. Can they community help me understand what I can do for a permanent fix for the issue?
