Here's the deal:
I can log in. Depending on what I do, it seems, I will crash within 5 minutes to several hours later. The problem started Wednesday, perhaps not coincidentally the day of the last update.
As it's starting to crash, I get this freeze-run-freeze-run pattern. It doesn't affect anything else on my computer that might be running. (And yes, I've tried running with no other applications, but that doesn't change things)
Things that seem to bring on crashes:
* Uploading textures
* Using ctrl-alt-mouse to zoom camera views
* Going into "appearance" mode
Error messages:
* Forgive me, I haven't written it down, but something about ADM somethingsomething AGP (or is it ADP ... AGM) video card...?
Steps taken to correct it that haven't worked:
* Cleared cache
* Minimized video options
* Reinstalled SL
* Updated video drivers
* Reinstalled Windows
Any ideas?
