I recently replaced my radeon 9250se with the radeon 9600xt. and the problem I now have can be seen here http://www.nimiy.com/monitor1.jpg and here http://www.nimiy.com/monitor2.jpg I need to add that the problem occurs as soon as I start the pc. but not always. usually it does but not every time. then when it does what I do is to switch the computer off again and then switch it back on. often this would solve the problem already and the pc will start normally showing no trace of the problem. after which I can use the computer normally, play games, anything without no visible problems at all. I can use the computer for all day and no problems would occur. even if I restarted the pc it would still work the same fine. but as soon as I switch the pc off then if I switch it back on the problem usually appears again. but not always. anyone have any ideas. could it be that my power supply is too weak? it's 300W.
