you are using a very old version of windows with current ATI graphics drivers
basicaly the old version of the desktop window manger is trying to use your graphics card and had a bug.
I think it was related to aero interface, it was fixed years ago but you need to install the service pack and all the updates or
turn off the hardware acceleration by stopping the service if you really want to not update your system
service name: Desktop Window Manager Session Manager service
you can disable the service, see below or problem should go away with after your windows system files are fully updated
