I have installed redhat enterprise linux 4 on dell poweredge 2800 server and it give display error "out of range". when i goto run level 3 and give the command below it gives the message displayed here.

[root@KMUCache /]# system-config-display
Trying with card: ATI Radeon 7000
Couldn't start X server on card 0
Couldn't start X server with old config, trying with a fresh configuration
Trying with card: ATI Radeon 7000

Those messages are incomplete. Please quote exact errors.

Make sure that /etc/X11/xorg.conf is appropriate for your display. "out of range" errors usually mean that refresh rates and/or resolutions are bad.

Try just running startx after login.

whenever the system is restarted following errors appear on the screen.

Out of frequency range

Attention
Out of range
H:26.9 KHz V:42.8 Hz

and the system becomes un responsive i.e it would not let you to enter at any console.

That looks like an error from the monitor not the OS.
Certainly don't look anything like the errors reported in post #1.
What kind of monitor is this?

Edit xorg.conf and change the monitor section so it looks like this:
But the one you sent looks incomplete. Where, for eg, is the screen section? The server section? etc.
