I am trying to solve an on going problem with an AMD 1.8 system. I have a new Radeon 9200SE card installed and a new Optiquest Q95 monitor, running XP Home SP2 with 256MB Ram. I probably could double the RAM but the system is not running any high powered applications. It is used mostly for simple games, internet and email. All Windows updates have been installed including NET.Framework 1.1. The problem is the screen will fluctuate in size under any condition. That is I do not have to be running any software. I have adjusted the refresh rate (several times), installed the latest drivers and it will stabalize for a time and then start the fluctuation again after a reboot. It acts like the system is loosing power so I installed a UPS to no avail. Can anyone help me diagnose this problem? Thanks for any advice.
