X crashes and mouse stops working.

Description of problem:
Xfree will crash, the screen flashes blank for a couple of seconds,
and then will not come back on until I press a key. When this happens
the mouse stops working. Only way to fix that I have found is to reboot.
This is happening intermitently, sometimes it will happen whilst in
GDM and not having touched the computer yet. Othertimes it will
happen whilst doing any type of work. It has happened also whilst
logged in and not at the computer.
If you can advise me how to, I can try to get some sort of feedback in
the form of debug output or something.
I was thinking this could also be a Kernel/driver issue but not sure.
I'm using a Logitech USB mouse.
Option "Protocol" "IMPS/2"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "no"
Using radeon 7500.
VendorName "Videocard vendor"
BoardName "ATI Radeon 7000"
Note: X does not completely crash as it us still usable after the
blank screen, but mouse fails to work.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Actual Results: Screen blanks, and mouse fails to respond.
I can not find any way to reproduce this on demand :(
I have since found a little bit of output on some occasions when this
occurs. I get the following ouput sometimes:
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Error: Can't open display :0.0
xscreensaver: 07:21:24: 0: child pid 7273 (anemone) exited abnormally
Of course, start and end arent there, but the rest sure is. Also, I
can recreate this quite often if I leave the computer at the login GDM
screen and wait for a while after the screen switches blank.
I've recently changed from my USB mouse to a PS2 mouse as I was
recieving some USB related error messages when this bug occurs. Now
that I am on a ps2 mouse the screen blanking still happens, however
the mouse continues to work.
Furthermore, I think this bug is somehow related to XScreensaver as
sometimes when the described behaviour occurs the screen saver does
start for a brief time.
I'm changing the priority to high as the system is basially unusable
with the bug present. I recently converted my father to Fedora and
this would not have been possible if his system had the same issues.
I have an error SIMILAR to this where the screen blacks out [seems to
turn off all output to the monitor] after a certain period of time. I
need to either restart the computer to regain functionality or
SOMETIMES i can Ctrl-Alt-F7 or F8 and it will switch back into the X
session I had been running. Otherwise Ctrl-Alt-F1 doesnt even bring up
the shell, Ctrl-0Alt-Backspace doesnt restart X, and the keyboard
seems to not function [i know this because no keyboard lights go on
for Num/Caps lock]. It occurs after my installation of FC2 x86_64
today and I origianlly thought it may be the wrong monitor that I
specificed, but I returned to generic and it still occurs. I am
running a PCI ATI All-In-Wonder Radeon [i believe 7000 series] on a
FC2 AMD Athlon64 system with x86_64.
