help restarting an old 486 PC

[Gerardcjat]

This old 486 PC has been on a shelf for 10 year.
I re-started it today.
Lights , fans, etc ... goes up and the computer beep as the HD is missing.
The problem : Display is Black, saying : "NO SIGNAL"
The monitor is good, tested on another PC
The video card is a "stand alone" PCI / VGA card.

How comes that I do have AT LEAST the prompt from BIOS ??

What I am missing ?

NO Hard disk should not be a problem, should it ?

Is it possible that the video card died ** OR **
than an exhausted battery ( on the CM ) might be the problem ??

Thanks for the help.

You will probably find it helpful to do some background reading on how these old machines work:

Thanks, that helped.
Seems I have a memory parity problem
Will investigate further when I am back.
