I don't think you can exhaust RAM or VRAM in that way, because of FIFO and
because switching between already loaded apps in itself shouldn't change
memory usage. Unless perhaps you ran out of physical drive space for VRAM
but I'd expect worse than an explorer reset if that were the case. In any
case with explorer restarting again I'd think you'd be right back to the
same status so if your scenario were true Explorer should crash again
practically immediately unless you closed some apps to free up RAM or one of
the apps closed spontaneously during the crash.
I still tend to think that something you are running, or that is running
automatically, is invoking an old or otherwise incompatible DLL or other
shared file. Once it's crashed a different version begins to be used and all
is well again except for those running apps that are still linked to the NFG
file. A lot of programs come bundled with older versions of system or shared
files. Those files get loaded when the relevent program is run but other
subsequent apps you start, which may need functionality only provided in
newer versions of the same file, will also use the already loaded but
obsolete file. When an app calls a function (for example) that isn't
provided for in the file the problems start.
