Lenovo 700 Audio and Camera "not installed"

Windows Updated, now Audio Cards and Camera do not operate.  Message on Device Manager "Properties" for all devices is "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"    will not install new drivers, dowloaded from Lenovo, neither device is recognised, troubleshooter cannot solve, uninstall and reinstall fails.  Norton cannot find any viruses, Norton Power eraser fails half wy through. Any ideas
