I have owned an Axion 17' monitor for about 1 year now. In the past week I have noticed that periodically the monitor screen will start shaking. I have used teh same video drivers for a while and have not added new hardware. I checked the cables and they are fine. I own a CL Voodoo 2 and an ATI Rage Pro. I do have a set of ALtec LAnsing ACS 45.1 and the sub-woofer is unshielded. Could this be my problem? any suggestions?
