All monitors go blank and can't use the computer for a period of time
 

I need some help here. During church service, all of my monitor screens will suddenly go blank and after a couple of minutes, come back on. My first screen is the main monitor which is a Visio TV for the computer, the second screen is a Hitachi Projector and the third screen is a TV. Part of the screen that was on the third monitor will then show on the projector and the main monitor. I have attached the system information gathered by the DisplayLink Support Tool. I use EasyWorship 2009 to use the projector and extra TV. The extra TV is used for a foldback monitor for the people that are on stage. I have updated the drivers for the AMD Catalyst Radeon to 12.1. I have also updated the driver for the DisplayLink to 6.1 M2. I would like some help. Thank you. If this is the wrong section, I have also posted this under the Windows Software.

might be a power USB issue try to uinplug one and if the others are working then its a power issue.
