DVD Drive won't load driver in Vista

[leachim]

I have Vista with an LG DVD rw drive

Recently it has not been listed in My Computer and checking Device Manager, see that it has an exclamation sign next to it

Tried uninstalling and restarting when it looked for the driver, but would not load - I click on update driver, and it says an up to date driver exists.

It is set to boot from DVD and it does, but windows won't list it.

Hope someone has a fix

Thanks
