[ILUG-BOM] blurred display

the display on my screen is very blurred (both on command prompt and also the gui). all letters and even icons are very fuzzy. it's really hard to read anything on the comp. it all started after i installed mandrake9 on a blank partition. i'm currently using RedHat 7.3 besides mandrake9. it is on RHL 7.3 that i'm experiencing this problem. all entries in /etc/X11/XF86Config and /etc/X11/XF86Config-4 are correct. when i try to change the resolution of the screen using Xconfigurator, i get the foll msg at the end: "There is a problem with your X configuration. You may go back and modify your configuration or exit now".

is there any way to restore my X configuration, other than reinstallin RHL 7.3 plz help !!
