Hi,
I installed vista RC1 and everything is cool, but when i run the media
center it appears that it start to run but nothing happen, when i try to move
between windows by ALT+Tab i see the media center window and it is black but
when i click on it nothing change i still having my desktop background but
the mouse icon disappeared, looks like i'm in MC screen but wont able to load
correctly!

Any idea what is wrong here?

i removed the RC1 and re install it but again same problem.
My pc configuration are 2GB RAM, AMD Athlon 64 X2 Dual-Core, and NVIDIA
7800GTX and creative XFI XtremeMusic
