Aero missing after reboot!

[magiccharlie]

Been running Vista for weeks, no problems whatsoever. Rebooted my
machine last nite and when it booted up Aero was gone. No Aero-
related options in my personalize windows, etc.

Any ideas? I don't think I installed any programs recently.

Same thing is happening to me. Aero gets weird after a couple of hours and
the taskbar and startmenu become unusuable. When you restart, its gone to
Windows Basic, and everything works again. Problem has been reported to
Nvidia who made my Video Card.
