Random Screen Blank on startup all the Time.

[Ragone_Andrew]

I have posted to Bugzilla but have not gotten any replies. I am wondering if anyone is familiar with this problem: 

Description of problem:
I have an error where the screen blacks out [seems to turn off all
output to the monitor] after a certain period of time whether I am
activly using my system or it is idle. 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-Alt-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.

Version-Release number of selected component (if applicable):
default FC2 x86_64 release

How reproducible:
Always

Steps to Reproduce:
1. Install FC2 on x86_64
2. Boot up X and logon
3. Use the computer for 10-20 minutes or let it be idle and will find
the screen go blank
    

Actual Results:  Screen goes blank. Usually keyboard is unrepsonsive
to X restart commands or Shell keycodes.

Expected Results:  X continue to function normally. No reason for the
screen to go blank. The drivers and config SEEM to be correct as it
takes time for this issue to occue.

Additional info:

Have tried to reconfigure the monitor display. Didnt work.
