Thanks for the quick reply but this is not working either. The discrete gpu is not listed in the device manager, only Intel hd graphics. Can you offer any other suggestions?

For anyone that might be interested I was able to get it working by unplugging the cmos battery with the main battery and charger removed for several minutes. Then I installed Windows 7. It seems like the latest Windows 10 update is the culprit. Maybe it will get fixed one day.
