Intel HD 4000 / GT 640M issue of games going to black screen

[ccunnin71]

Hello,

I recently updated the family PC (Dell XPS all-in-one)to Windows 10. I have found issues with most games running in full screen mode. I get only black screen with sound as the game runs in the background. If I run it in window mode graphics work fine; Portal 2, Dungeon Defenders, StarWars Battlefront II... all old games so not stressing the machine. I have many more but I keep them aligned with what the machine can handle.

I have the latest graphic's drivers (win10\64bit) and I have spent a lot of time trying to tweak the Geforce Control Panel to no avail. PC works fine until game is launched in full screen mode and then only audio. Lame... Not willing to lower my expectations or reinstall windows 10. I will fall back to Window 8.1 only as a last resort (suck). At my wits end on this issue as numerous Google searches have not helped.

The following work around was not effective for me but was suggested;
1. start -> Control Panel
2. click NVIDIA Control Panel
3. On the left select 3D Settings -> Manage 3D Settings
4. On the right select the Program Settings Tab at the top
5. Click Add to add a program
6. Browse to the find or browse to the <game name>.exe
7. Change the drop down from "Use global setting"
to "High performance NVIDIA Processor"

I have posted this issue at six different forums I respect. Might be the holiday's but no light bulbs are going on for this one.
