Alieware-can it be refunded?

I bought an Alienware aurora R3 last Christmas, so its not even a year old. Now I m freaking pissed of it 65% of the time i had it I am just trying to fix problems. First my graphics card had a problem my screen was on blue lines, and many more shuts down unecpectedly and also more than 5 times I loose all my imformation and games and it doesnt allow you to install your own windows too i wanted to change from 8 to 7 but it says no drivers where found please choose but u cant choose! Once everything was OK I shutdown and then after a while i put it on and screen just flashes from black to grey and simply you can do nothing about it. Then it said it will try to fix the problems then no problems where detected and then the machine reinstalled i thought only disc C would be deleted because i had disc D as well , it actually made then into 1 and deleted everything! then my screen was half the size again and all those Alienware stuff like the change color option nothing i had i had to make everything again contact them which will take me another week.
So many problems occured I have still not mentioned because it will take me a day. Guys Dont buy Alienware I have checked forums some people say its good some its shite but i choosed to buy it because I was looking it every day for 3!!! years!! and at the end very disapointed very dissapointed.

OK so my Question- Can I refund (return) This Alieware and get money back. I have all disks and things with it they gave me condition as new refurbished (graphics card being changed with the same one) The only thing I m missing is the box it came with all carton boxes are binned. Can i still return it?
