after few years of stopping, I tried to resume my old Elite 8200. (s/n personal information removed).
The machine starts, checks the optical device, but the monitor (plugged on the on-board socket) does not starts. No beep, all lights on the main board green, and after 20 seconds, the processor fan starts at very high speed.
Some help ? Thanks.

@ComputerFulvio -- something has failed.
When one powers-on the computer, the POST (Power On Self Test) starts to run.
It speeds-up the fan to 100% speed, and 100% noise, to check that the fan is working.
Normally, the POST then tells the fan to slow down (and become quiet).
But, something is failing -- the POST is not successfully completing.
Take the computer to a technician, for professional trouble-shooting.

Thanks for your reply.
I know that POST normally when something doesn,t functions well, it emits a sequence of beep, which indicates the probable origin of the trouble. Apparently all is ok, but nothing happens...
Nothing to do, for understanding better which may be the cause of the malfunctioning ?

No, everything is not OK. A single "beep" indicates successful completion of the POST.
Is there a pattern to that sequence, e.g., "short-short-pause-long-long-long-pause-pause-pause"?
Researching that sequence will reveal what the POST is trying to tell you.

Thank you Itsmyname, for your replies and patience ,
I agree completely with you, but the first problem is just that the POST doesn't tell me anything ! The PC starts, does a check of the optical player, but after this, there are no beeps, no red leds on the mobo, nothing of nothing... only a blank screen.
