i switch to whitebox 3.0(gnome) ...i cant find how to change refresh rate..can you help me??

Why would 80hz be doing anything to your monitor.
Unless you have a really old monitor, that was made in the 80's.
80hz won't hurt your montor in any way.
In fact, if the monitor hurts your eyes from looking at it to long, you should up the refresh rate, so you don't get sreen flicker.

I use kde, so I don't know how to change it in Gnome.

O.K. I switched over to Gnome.
Go to Preferences>screen resolution.
There you can change the refresh rate.

my monitor is 107E philips ...75 is the maximum refresh rate according to the manual or damaged your monitor...

You can also manually change it in /etc/X11/XF86Config-4 (at least I think you can, if FC uses xfree, if it uses xorg there should be a similar file at the same location). Anyways, look for:
Section "Monitor"
then find the 'HorizSync' and 'VertRefresh' options, where you can set the ranges for the refresh rate. CRT monitors should not be too hard to set up, but my LCD took quite a while.

edit: you can only edit this file as root!
