This was reuploaded from my previous account: "modshows" which I have deleted a few days ago.

Keystroke at boot: Command-Option-P-R

Non-volatile random access memory (NVRAM) is the general name used to describe any type of random access memory which does not lose its information when power is turned off.

Parameter RAM, a small amount of non-volatile random access memory (NVRAM) used on Apple Macintosh machines to store configuration information

I just purchased a used iMac and it's been switched to Microsoft Word and they guy who sold it to me doesn't remember his password. we've tried guessing but haven't gotten it right. If you can PLEASE help me switch it from Microsoft back to Mac & more importantly GET IN, that would be greatly appreciated!! PLEASEEE!!!!! & THANK YOU! (:

@graciem616 have you tried holding the option key when turning on the computer and selecting Macintosh HD?

Umm when I did this, it had the apple symbol, the error symbol (A circle with a line across it) and a file with a question mark on it...HELP!

@hleepymanzilla your computer filesystem in corrupt, you will have to format. Resetting the PRAM and NVRAM has nothing to do with this, it is just coincidental that it finally found out you had some corrupt files that weren't addressed before.
