Hi markfrompetaluma,

If your vintage iMac's displaying lines and isn't booting up like it's supposed to, that's not conducive for use. I'll do my best to help you though.

Reset NVRAM (PRAM) -- Resetting can help with display issues.

Try safe mode if your Mac doesn‘t finish starting up -- The title is pretty informative and can help getting past the Apple loading bar to your desktop.

Take care and thanks for using Apple Support Communities.!
