Acer Aspire 5920 will not start up

Question

when its turned on the Acer screen is visible for 1 second. The screen goes blank with a flashing/winking cursor in the top left corner. I tried alt/F10 and even though the option to restore factory settings appears, "please wait a moment" will stay on for hours and no end result. It is 8 months old and was brand new when purchased. Unfortunately i dont have he receipt or contact details of the company where it was purchased.
