Thanks.
Well - I checked first on DirectX. Running version 12, so no issue there.
Then I went to update the AMD Graphics Drivers. And that's when the fun started. It turns out that AMD has an automatic updater that you can download, BUT it's not smart enough to determine if you have the proper Windoze updates (which you need), or have run a clean-up utility (which you apparently have to do) before you install them. I had neither.
So there I sat with blank screens and a boat anchor box. Luckily, I was able to get a real person from AMD on the phone (he was real good and patient) to step thru the recovery process.So far this morning, no issues, but I haven't been using the effects function much yet. We shall see.
Again, thanks!!!
