Talking GUI not working after changing resolution in Centos 5.4 on Dell Optiplex 280

After installing a Dell Optilex 280 desktop with Centos 5.4, I configured sendamil, squid and all the extras I needed for a proxy and email server. All was fine until I switched the machine off. I had changed the resolution before and all was working fine. Now I have lost my gui , the system starts O.K but goes blank after "starting udev". I can use webmin to administer the server from a nother desktop/laptop but the monitor is totally blank. I tried most configurations on the /etc/X11/xorg.conf file even tried to create a new one using X -configure but still nothing changed. I cant afford to reinstall because of the time it takes to update the box, our broadband connections are so expensive this end of the world (Zimbabwe) and not so effecient. I have looked at the logs and tried to google but the solutions wont work for me? I suspect there could be an issue with the intel graphics adapter?? Thanks in advance for your help.

connect from remote to the machine using ssh and check /var/log/Xorg.0.log for errors or post this logfile here.

boot into SINGLE user mode
and from the terminal tyr this
mv /etc/X11/xorg.conf  /etc/X11/xorg.conf.old
and reboot as normal

or run the command from the install cd in RESCUE mode

Thanks all for your responses, I had already done the suggested fixes such as moving the old xorg.conf and rebooting, what I can do for now is figure out how I can send the log file. Thanks
