Is it possible to reset my computer to factory settings without any access to the administrator part of my computer? I lost my password so the only access I have on my computer is to my guest account. If not , is there a way to reset my password without knowing my current password?

Guess it depends on what you mean by "administrator part." If you mean that you lost your BIOS password you're pretty much out of luck. But since you mention your "guest account" I'm guessing that you mean you can boot Windows. So, boot to the Recovery partition or to your Recovery DVDs or CDs to do the "recover/reset/restore to factory defaults." You can find specifics on how to do so on the PC manufacturer's web site and/or in documentation you got with it.
