Z50-70 now unuseable following driver updates!

2018-04-01, 14:31 PM

After numerous problems over the last few months with my Z50-70 and two clean OS re-installs the laptop was still running slow. Yesterday I updated the drivers from Lenovos website and installed their Vantage and system updates apps, today the laptop will eventually turn on but is very unresponsive. The screen keeps refreshing every minute or so.

You can roll back to a previous drive. Look for the button in Device Manager for the device. Whether is a video driver or something else I can't be certain. That is an AMD system as I recall.
