I am using fedora core 3 x86_64 edition. I have a Gateway EV910C monitor using on board VGA port. I am having problem that when it is booting up and also during the login screen, my monitor shuts off and says

Out of Frequency
HF 24.5 KHz
VF 33.0 KHz

Operating
HF 30- 95 KHz
VF 50- 160 KHz

and it will not operate? any suggestion to this problem?

TRy chaing the refresh rate (mmaybe do a google for your monitooor, and find the right setting then edit your /etc/X11/xorg.conf file and put in the new rate)
