Wow dude, chill out.
First off, lets ask a few questions:
1) Did you just install esf and its causing this problem from the first time u played it? --or--
2) Have you had esf for a while and it is just NOW happening? (which means, in previous times playing, it never crashed until recently).
If you answered yes to question #1, then my guess is you have a problem with your in-game video settings. Check your video settings from the ESF configuration menu. What type of video mode is currently selected. Sometimes with the older geforce cards, its not a good idea to run OpenGL. I remember when I had my geforce 2 GTS-PRO and tried running OpenGL, it would crash during beam attacks. So I switched to the other methods (not sure what they are-- I currently run OpenGL with my newer vid card). Try running your game in another type f video mode and make your resolution no less than 800x600 and no more than 1027x768 (or similar resolution, I don't remember the exact numbers but I know its close to that). If this doesn't fix it, I think there are 3 different video modes, so try the last one if you've done the other two with no success.
If you answered yes to question #2 from above, then my suggestion is to do a clean uninstall and reinstall. Backu-up any models you currently have replacing the originals. I don't know how ESF works with its registry entries, and whether those would have any remaining effects to your newly installed esf. I doubt they would carry data on your video modes or preference settings.
If these suggestions don't help, then try to be more specific with your esf game. List what video mode you use, your resolution, what sound options you have checked (HEX/HEA I think are the two hardware modes) and these could both affect your game if your sound clips aren't initializing correctly. So give the specs on your video and sound preferences.
