Ok, run a DXDIAG
to do that go to your start button, click on run, type in DXDIAG
run all the tests
save a log file
post the log here
also check your shortcut properties again..
rightclick on your shortcut for SFC 3
click properties
click compatibility tab
put a check in "Disable visual themes" leaving all other boxes blank
click OK
try game
if you are still having errors, please post a Direct X log report...
there must be something you are missing in the setup procedures listed above...
Direct X Log will look at your windows region settings.. if your region setting is different than OS Language, it causes Vid Card discrepencies and game crash.
Also, you may want to go into services.msc and disable UPNP (Universal Plug and Play) and also go into MSCONFIG and turn off any mouse software you have running in the background (in startup tab).. especially Logitech mouse software...
