ATI Radeon 7500 startup problem
 

I have just installed Redhat without any problems at all. But when I boot up Redhat, it starts the services/etc. fine, but when it is done doing all of that, my monitor turns goes to standby meaning that no input is being sent from the OS. BTW, my graphics card is PCI if that might help. Any thanks for a first time user will be greatly appreciated :)
