I have recently upgraded to Windows 8.1. However, after doing this I have encountered problems with several of my previously installed computer games, and even a small error within Windows Movie Maker. I have read up on this subject, and after trying to find my drivers using DXDIAG this is what I found. (See attached screenshot). Since my DXDIAG says that it only uses a Microsoft Basic Display Driver and does not give me a manufacturer's name, I am not sure what to do. I am operating on a Samsung Laptop by the way. If anyone has an answer to this or needs more information please let me know. Thank you!
