Installed a new card the other day, the Nvidia GeForce 4 MX440 AGP. I had previous issues with installation until I changed "PNP OS" to NO in the bios. I was still getting the occassional screen freeze and it just got worse after I downloaded a graphics intensive demo game. The colors came up a little wacky sometimes and other times not. Then it started to freeze my system at random times playing it. Then I noticed my system was also freezing when playing certain shockwave games. I'm confident it's the video card as none of the problems occurred before installing the new card. I've updated to the latest Nvidia drivers and just now installed the latest AGP port for the chipset on my motherboard. I'll monitor and see if that helps. Anyone have any other ideas?
