Multiple display - frozen - usb 3.0 docking targus - zenbook asus - windows 8

[Mario_Lanz]

Hello

I'm using a Asus Zenbook with Windows 8 (64-bit) together with a Targus 3.0 USB Docking (http://www.targus.com/uk/product_det...sp?sku=ACP71EU).

I've pluged in 2 24" screens at the docking @ 1920x1080.

As of sudden the notebook lost the connection to the sound, ethernet (lan) and the monitors. In fact, the monitors are frozen. Even after two days, the still show the same frozen "screen/desktop".

Meanwhile I've connected one of the monitors directly to the HDMI port on the notebook. This port is working normally.

Funny enoough - the pluged in USB Keyboard and Mouse and the docking are still working. Also the other USB devices.

Conclusion
Not working through targus docking:
- LAN
- Sound
- Monitors

Working:
- Mouse (USB)
- Keyboard (USB)
- Other USB Devices
Direct from Ultrabook
- HDMI

Asus Zenbook UX32VD:
Windows 8 (64-Bit)
10GB RAM
Intel SSD 240GB

All drivers from Asus are the Windows 8 ones.
I've just updated the nvidia driver to 310.90 a few days ago.

In addition I'm using sometimes also a Toshiba dyna docking (USB 3.0 too).

I'm searching for a possible cause.
I'm not sure, if the newes nvidia driver is causing the problem (http://www.displaylink.org/forum/showthread.php?t=2198)

Thanks a lot for advices
