I've had this model (Compaq Presario F756nr notebook; bought new) for about two years now and it runs Windows Vista Home Premium. My problem started several weeks ago when I noticed that everything was so much slower; internet pages would freeze or not even load, would boot up much slower, etc. So, I eventually used my recovery discs(3 of them) to restore to factory settings but now when I turn on the computer it barely makes it to the desktop without freezing up. Usually when I start the computer up, it will go past the boot up screen and then say windows failed to start and recommends running startup repair. But when I run startup repair, it says it can't fix "the problem". Or, I can choose to start Windows normally and it will usually freeze in the process before getting to the desktop. Does anyone have an idea or ideas of what I could possibly do next. I don't have the money for another laptop or expensive repairs. I not sure if the computer will make it through the recovery disks again without freezing up. I did manage to run a disk check and memory check from the boot up screen that showed no problems so, I don't know what to do next or what the computer will let me do next.
