I have a GeForce4 MX440 and my system also frequently requires a hard power-off shutdown
From other thread! .....
More worrying is .......
This 0.9 beta is behaving like the N417,0,9,14 ........... ie.
Restart after a setting change, frequently locks up my computer, requiring a reboot.
This seemed to be cured with GA Version N419,0,9,156 ...... but now it's back again!
