I just upgraded my PC from an ABIT KT7-raid with a 1GHZ Thunderbird to an Iwill Xp333-r with an XP1800 processor. As soon as I boote the system up. I noticed some wierd video. First of all when I was editing the bios, I notice that there were some squair blocks randomly scattered on the screen . The second thing I noticed was that vertical lines were appearing on my screen when I was in windows 2K. I had no problem playing Unreal. All other applications seem to be working fine. Is there a compatabiltiy issue with the Raedon 7200 and the New XP system? Or does this sound like bad ram?, motherboard, or processor?
