You mean you was installing the video card drivers off a usb pen ??

Are you sure the drivers are correct ?

 

from a cd that came with the usb card

 

I don't understand what u r doing?
R u installing a USB card or Video card?

 

installing usb external video/tvcard, and i get the msg up when i install the driver from the cd

 

often its best to install the driver software first then plug in the device afterwards when using USB devices. You will probably need to use roll back to make this work on yours.

 

i done it like this the 2nd time but that when i got this msg, sorry but wots roll back?

 

In control panel, then system, then click hardware, then device manager, you can double click on the item, then there's an option to roll back the driver.
