Alienware M15 (Thin) Incredibly Slow

So, we've all had that old laptop/computer that gets so run down that it runs at a snails pace, you open up and application and it takes 5 mins to actually appear, or you open-up a web browser and its takes 3-6 mins to fire up. Well that is what your brand new Alienware M15 is like out of the box. 

I've had it a few months now and it goes through phases of being utterly useless, on start up it take 5-15 minuets before you can do anything. Chrome then take 5 mins to warm up before it responds, when you run applications nothing happens........... 5 mins later the program opens up. Any suggestions on if or how it might be fixed would be really helpful. 

Otherwise save yourself some money and duck tape a 6 gb graphics card to the old windows 95 pc you have sitting in the corner of your office, will probably be a lot quicker.
