I used to be able to play games on my computer just fine, then my computer crashed and i had to get a new hard drive. after my father reinstalled vista and all of the drivers, the games didn't work.
some games i played are:
star wars battle front ~ used to work, now when i start it, it appears in the task bar, but it doesn't show up and my mouse disappears
NWN ~ it just doesn't show up when started
Second Life Viewer 2 ~ only gets to "Initializing VFS" and freezes.
Second Life Viewer 1.23 ~ finishes loading but doesn't show up, it appears in the processes tab on the task manager though
also Second life works on my friends computer (we both have the same computer)
though i haven't tried the other games
I have tried, on all games, uninstalling and reinstalling
