Gray screen with white text need to restart computer hold down power button error

my iMac would not boot. It starts with a gray screen with white text saying "you need to restart your computer, hold down the power button, then press the power button." It has other languages saying the same thing. This happens every time I power on the computer. Nothing else.

I Tried command option r for the recovery and that didn't work. I also tried the command option p r keys and that didn't work.

please help me get my iMac running again.

Best regards.

Remove any non Apple perhiperals, disks, keyboards, mice if you have any. Then try a Safe Boot Try safe mode if your Mac doesn't finish starting up - Apple Support

I Followed your links but my problem exceeds them. The kernel panic is constantly there no matter what I try. In fact recently I did a NVPRam reset and my iMac wouldn't stop chiming. Then I got a blinking question after I did a command option r p and then it went to a white screen. I tried the shift button nothing happens. I tried the option r and nothing happens goes right back to the kernel panic. I'm confused as to what else to do.
