Well, this is the story:
I bought a computer from this reseller, and then also sent back this motherboard.
I believe i did make those scratches myself, but thats not the problem.
The problem is that before i sent the motherboard back to the reseller, it worked perfectly.
It was when they replaced my graphic cards which was the real issue they also found these scratches and told me that my computer would not maybe run stable on this motherboard due to them.
Then they replace my graphic cards and the motherboard.
And when i am trying to start my motherboard now it only starts the computer for about 7 seconds and then it turns off again. Seems like the reseller (which is a big one in my country) damaged it in some way just to make sure i wouldnt be able to use it again, due to the fact that it worked before i sent it in to them. What should I do?
So the problem isnt really that I need to have to warranty, the problem is that now when I got it back its not even starting in more then 7 seconds with that motherboard, but before i sent it in to them it worked perfectly.
