There is a bug i think when using ATI cards (we always blame the
graphics cards!)... after much googling, on a friends machine with the
machine problem i came across this to add to the end
of /etc/X11/xorg.conf

Section "ServerFlags"
 Option "BlankTime" "0"
 Option "StandbyTime" "0"
 Option "SuspendTime" "0"
 Option "OffTime" "0"

Worked for me so you can give it a try.
