NoVideo

Hello,

I am new to linux.
I just installed a dual boot, win2k and redhat7.1
I used auto installation for linux. When I boot into it the screen starts flickering. It looks like it’s changing resolution. It’s just black.
It works at the command prompt, but the gui does not start up.

I reinstalled it many times with different settings for ide and monitor, still same thing
Any ideas anyone?
