Windows 7: HELP!!! Device Driver software not successfully intalled

Hi
I have a Windows 7 Ultimate 32 bit OS on my PC Desktop.
I have a SmartBro Internet connection broadband.

I was just using my PC yesterday and when i opened it today it had an error message that says "Device Driver software not successfully installed"
so I tried opening the device manager..
I found out in the "Other Devices" when i clicked it it oped a sub option that says "Ethernet Controller" and that Ethernet Controller has an Exclamation point on it on a Yellow triangle backgound...

because of this I cant connect to the internet..
right now im using my aunts laptop..

Please... Help me with this.



I've tried searching the internet about this error message, its just difficult finding the solution about this.

Save the new driver to a thumb drive, on another computer

Even though it should be enabled by default, check to see if automatic driver updates is enabled:

Windows 7 automatic driver update tool

Go to Device Manager, right click the problem device, and choose Update Driver, see if Windows will find it. If not, go to the problem device again but this time, double click on it. In the window that opens, go to Driver tab then Uninstall and Uninstall Driver, and reboot. This may help get it back.
