Hi,
Did you run the Windows 8.1 Upgrade Assistant before upgrading? Did you see any incompatible information?
I would like to suggest you update all your drivers especially video card driver to check the result:
1.Right click start button and the click Device Manager.
2.On the Device manager windows, you will see a section called " Display adapter ", click on it.
Select one of the following:
3.Now right click on the video card shown and select " Update Driver Software ".
Or
4.To update the drivers manually, write down the name of the video card from the "Device manager" menu under "Display adapter". Go to the manufacturer's website, get the proper driver to install your own computer and
5.Restart the computer to take effect.
