Screen blanks and reappears only when playing games

Archived from groups: microsoft.public.windowsxp.video (More info?)

I've got a bit of an odd problem. ONLY while playing games like SWAT4,
MADAGASCAR, THE INCREDIBLES, my screen blanks and reappears constantly.
While using it for internet, or other applications I don't have any
issues. These games do require Direct X 9.0(C) which I have. I have
the latest ATI Radeon Drivers CATALYST 5. Any help would be
appreciated.

Currently running Windows XP Pro SP 1.
