Can MOBO drivers/software be rolled back or can older versions be successfully overwritten on top of newer versions?Reason: I recently update from 15.25_nforce64 to 15.51_nforce64. One of the updates had to do with the ethernet connection and it also placed 2 new services in the Vista Services which I have tried both started and disabled to no effect. I am now unable to start my O&O 8.6 64. One of the services is a firewall of some sort and this could be an PIV4 versus IPV6 issue. Have been in touch with O&O service, and working on this but thought I'd ask. No other programs seem affected.Thanks.

You can rollback drivers as long as the feature is enabled (which it is by default). If for some reason that doesn't work you'll have to first uninstall the driver in order to then be able to reinstall the old driver.
