Major problems with latest Windows Driver (6.4)

I have a laptop with an nVidia 560 GTX video card and Win7 x64. I'm using both the external display on the nVidia card, and an additional external display with the DisplayLink card.

I've installed V6.3 of the driver, but it causes bad problems. It crashes the nVidia video card upon each reboot, and also when the external nVidia monitor on the HDMI is connected (it does so even if the displaylink adapter is not connected to the laptop). When I boot with all monitors connected, I get no cursor on the nVidia monitors, only on the DisplayLink, but then the PC crashes.

Windows reliability monitor reports a myriad of "Video Hardware Failure" problems, from which the computer eventually recovers (no BSOD), after about 60s during which there's no video from any adapter.

I went back to driver V6.2 and all the problems disappeared. The system works fine, I can boot with all monitors connected, I can disconnect and reconnect any external monitors, with no problem. Is it possible that changes made in 6.3 somehow broke compatibility for laptops with nVidia cards?

Thanks,
