my video card has been going weird lately and there are two significant problems which has been occuring. First of all the video card im using is ATI Radeon 9200. Whenever i play games which takes up the whole screen that game will automatically minimize itself and if i click on the minimized bar once it will just minimize itself again, so what i have to do now is rapidly clicking on the minimized bar and sometimes the game will pop up. When i play the game WarcraftIII: The frozen throne, the game sometimes slow down instantly and when i manually alt-tab the game it has a popup window which says something like the video card has been restarted because it wasnt responding and the resolution of the screen will become 800 x 600 which before it was 1280 x 1024 but the color doesnt change.
The second problem is that whenever i play videos, no matter if its .avi or .mpg it sometimes have no picture and only sound. What i have to do to overcome that problem is to goto the ATI toolbar and duplicate/un-duplicate the primary display. I still dont know what is causing those problems and can you please help. Thank you very much.
