I don’t know about those particular games, but normally in most of the games (not all) the main menus appear in 640x480 (low bit depth). That could be your problem. Just set the desktop resolution (in windows) to 640x480 and adjust the monitor settings to fit the screen & so on (if you have a digital monitor then the monitor will remember the settings for 640x480 / if you have a monitor with knobs to adjust the size , position….. then set the screen using the software which came with the VGA card) . After that switch to your normal resolution. Afterwards when ever you run the games it should look okey.
I hope this helps
