Error on playing with windows 7

My computer is a new computer, windows 7 but i have problems playing on it. whenever i access my character, my screen would start to flicker or it would freeze, then i would have a blank dark screen and then it recovers but it will say : graphic driver has crashed and successfully recovered, i dont have other problems playing on the official server. is there a way to fix it?

This happens to me sometimes ,too (since I use Windows 7 too). Just change the screen size (Alt+Enter), or restart the client. Just remember that some really graphic skills cause that to happen in large maps, particularly the fm.
