Pentium 4 2 Gigahertz 768 MB RAM ATI Radeon 9800 Pro 128MB I have connected a CRT monitor, and an LCD display to my Radeon (either both together or one at a time) and booted Windows. From time to time, the display will cut out entirely. There's no sync signal going to the monitor - you can tell because my monitors behave the same way when a cable is unplugged. The output is black for about half a second, then it kicks in again. Sometimes it flashes on/off at about 1 Hertz, but it's not completely regular. All my power cables are plugged in tightly, and the cables are secure. I've tested both monitors with another computer - no problem. It happens sometimes during the BIOS boot screen and particularly under Windows. I can make it less likely by winding down the 'Hardware Acceleration' property, and make it stop altogether by disabling all acceleration. Obviously this means I can no longer play Doom 3...

I had that same problem (but on a 9000 card). It turned out it was the actual on/off button on the older monitor I had. As the monitor heated up and cooled down, the connection as well. This was a monitor that was almost always on. worth another peek.

I have a similar issue with my 9800 but its with the TV out, I only use the S video connection to my TV and intermittently it cuts out, sometimes several times, then going away, sometimes just cuts out and doesn't come back. No amount of playing with cables helps. I have to restart the computer when that happens.

Have you plugged a plug from the power supply into it?
