new Elimina Pro Series having problems

Hi, I'm new here and I'm not expert in disassemble laptops so I need your help.
I've bought a Elimina Pro Series laptops with the components that I'm gonna copy here at the end of the message.
Everything went okay with the delivery and the first installations but I had some problems a week ago. I mean, I was just watching a video on youtube and suddenly the screen got stuck and appeared many horizontal lines. Today I was just using chrome or doing simple stuffs and the screen frozed up and became black. In both times I just pressed the power on/off button to restart the screen and evreything was ok.
What should I do now?
I've read that it may be a overheating problem or maybe a defective processor.

Please help me I really need your help!

I'm sorry if some components are in italian, but I cannot find a way to easy copy and paste it in english even if I login to pcspecialist.co.uk. Anyway I think everyone can understand the main components.
