Glad you guys got this figured out :)
Just to get one last word in on the OT
bit I rudely started previously ...
Problem is that it is not always just "some cards" ... it is "some cards and 3rd party software". It can be some mostly harmless widget addon the user likes and forgot was installed.. but it also does the same calls that ENB does which cause windows to say... access denied.
Also in many cases of ENB not working then it is some DirectX dependency that is not installed... again something that is annoying, and will help create this black box type scenario.
All true, but with more than five or so decent records for a given issue, a rough pattern could emerge ... not to mention other interesting things coming from tying certain issues to certain hardware. As the sample of records increases for a given issue, we are likely to learn something interesting. One thing that is certain: we won't learn anything without capturing the relationship (well, those of us without "total recall" anyway ;) )
I would love a database on GPU:issue data relating to some specific issues relevant on these forums ... probably a bit of a lofty goal, but .......
