Does your graphics card have its own dedicated memory or is it sharing with
the main system memory. If its sharing, you likely need a card with its own
dedicated memory and I wouldn't go for anything less than 64MB.

If you have a card with dedicated memory of sufficient quantity and main
system memory is 128MB or more, you may have something hanging the system.
You need to check for errors in Even Log that might correspond to the time
when you have this issue. Open Control Panel, go to Administrative Tools,
open Event Viewer. If you see errors that seem to correspond, double click,
the information inside may give a clue as to the source of the issue.
