Power Button - No Power

Aurora R3, about 18 months old. Working fine then powers off. Push power button and nothing happens. Push button by power cord and nothing happens. Changed fuse, tried different power cord and nothing happens.

The computer is not powering up at all, I do not expect this from a computer this age. If anyone has any ideas let me know, if not can someone from Alienware/Dell let me know who to contact regarding a claim under the Sales of Goods Act please? A computer this age should be working with no problems and I have NO intentions of phoning a premium rate line, nor one which will mean having to ask the call centre staff what they are saying because I cannot understand their accent.

Sorry Alienware/Dell but this is unacceptable
