My early 2009 20” iMac will not turn on. When I press the power button it beeps 5 times. Please help.
I counted again....it was only 4. How do I fix this. I don’t know anything about computers. Your help will be greatly appreciated.

Five tones are you sure? Here's an Apple T/N on the tone codes: About Mac startup tones

5 beeps = Bad checksum for the ROM boot block
Reference: Macintosh Beep Codes
Good catch @mayer !
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
