LCD screen blacking out



Hello,

I just bought myself a 19" Samsung 940B LCD monitor. It is conected to the
DVI connector of my computer's video card, an ATI Radeon X800XT Platinum. I
have installed the appropriate Samsung drivers for the monitor as well as
the latest Catalyst drivers from ATI for the video card.

My problem is that when the PC has been on for a few hours, the screen
begins to become blocky with sections blacking out until the whole screen
blacks out. My screens settings are 1280 X 1024 pixels with color quality
set at "Highest (32 bit)". The screens refresh rate is set at the
recommended 60 Hertz. Is there something that can be done about this? Has
anyone else had this experience?

Thanks
Shane
