I finally got computer to working after 2 RMAs and 1 non-faulty item, almost wasting Â£25 by sending it to shop.
Yesturday, I decided to replug all sockets and checked manual. I turned on pc... I saw a Blue lights Of Life! It was running and fans was running so loudly but I can bear it.
Thanks for all your help!
