seemingly no connection between screen en pc

hey

i have a problem. after quite a time not using my computer (i didn't
have a screen), i bought a screen, which i tested on another system.
the screen worked perfectly. still, after plugging it in into my vga,
the computer starts up, i hear noise, but the monitor doesn't seem to
have connection with the pc. so i gave my vga to check at local
computer store, and they said it workes ok.
so my question is, what can be the problem?

can anyone help?

thanks a lot

Your new screen might not support the resolution and/or refresh rate you
have selected. When starting your computer push f8 and select either safe
mode or vga mode.
