My computer is killing it self?

Ok for the past few weeks my computer has been slowly dying and iv'e come to the conclusion to restore it to when i got it out of the box. The thing is, i dont know how to do it. When im in the restore section i can only restore to like 3 days ago. Also when i turn my computer on it doesnt tell me Alt + F11 or anything like that.

How do i restore it to factory settings? Its an HP Pavilion dv4 1275mx to be exact.

EDIT: It didnt come with any discs.

YOu can restore to factory specs using this information. If it does not work, I will try to help you find more current information.
