Crashed And Now Won't Boot?

Ok so my computer was running sluggish before it eventually totally froze up. I reset the laptop (dell inspiron duo) and now everytime after going through dell screen/bios it tells me that "windows failed to start. A recent hardware or software change may be the cause" or something like that and gives me the option to load either run windows normally or launch startup repair.No matter which option I choose I get windows is loading files and a White loading bar at the bottom of the page. Once this is complete the Microsoft green loading bar, no logo, will run through once before taking me to a blue screen which appears to be some kind of back ground. There's a dove carrying a branch and some White lines/lighting effects. This isn't my home screen and all that I can do is move the cursor around.

Nothing else happens and there is none of the usual start up behaviour.As far as I am aware there is no malware and the only new software that has been installed was the drivers to use an xbox controller with the pc via plug and play which was around 12 hours ago and the machine has since been turned on and off without problem up until now.
