I just rebuilt my computer with an Aopen KT600 mobo and an XP 3200 processor. Everything works great but during the POST and XP welcome screen the picture is shrunk about and inch from the outside and there are white bars on the side. It also does this when a game first starts to load. Other than that no video problems. I reformatted the drive with the rebuild and used Catalyst 4.4 drivers. This didnt happen right off. I think it was after I installe the Leadtek TV tuner card but Im not sure. I used different video drivers but it still happens.
