My system behaves a bit strange. Applications sometimes won't display bits of the graphics and sometimes gives me the error messages above. When clicking OK on the error message dialogs Windows starts doing all sorts of weird things. The taskbar moves to the top of the screen and most of the windows are not redrawn correctly. When moving the mouse pointer around I see random changes in the graphics. Moving large areas of one color etc. Most of the time the problem goes away, at least for the moment, when I close _any_ of the open applications.
I am running Windows 2000 Server with all available SPs. As far as I can tell, I am not low on memory (the system has 512 Mb and the task manager tells me that the memory in use is nowhere near that).
The graphics card is a ATI Rage 128 Ultra (I think, maybe a "pro" should be inserted too), it has 16 Mb. I have been blaming this card for the failures so far :) Nut I have no real evidence and it didn't help to upgrade the drivers.
I don't know where to start looking actually. Any help greatly appreciated.
