Acer aspire VN7-592G won't power on (no led)

Hello,

I bought a VN7-592G a month ago, and upon reception I replaced the HDD with a SSD that I already got from before. Everything worked fine, I could do all I wanted with the computer for the whole month.

Today, during a gaming session, the computer stopped suddenly (no BSoD, nothing, just shutdown). I thought it was the computer overheating, because it looked like the only possible explanation to such a shutdown, but the MB wasn't hot at all when I opened it to check.

Now nothing happens when I try to turn the computer on, and the power light won't even turn on when I plug the AC in the computer (it was plugged in and the light was on when it shut down).
