Try driver cleaner. You can get it here
along with other driver versions. Make sure you read the readme on how to properly use it, uninstall your current drivers first, safe mode, make sure you follow every step. It's possible that your old drivers are conflicting with the new ones, and this should fix that.
You could try 158.27 or a similar driver, and see if that fixes the problem, without going all the way back to release 94.
Also when did you update your driver? It could have been before 162.18 was final and whql.
