Try starting up windows with NO TSR's running anywhere, started either
before or after windows starts.  Don't start any applications.  Just close
down windows as soon as it comes up.  See if it hangs in this case.

One possible problem with a hang like this is that some other program was
doing some sort of trapping of interrupts or similar, and the sequence of
how things that were done get undone is not properly handled.

If this turns out to be the problem, then probably the real culprit is the
design of the BIOS and/or MS-DOS for not having provided all the necessary
services that would make it unnecessary for programs to play tricks with
interrupts and other things just to get the functionality their application
needs.  I have had to resort to such tricks too often myself.  I'd much
rather not do it, but it is either the only way, or the alternatives are
too damned slow.

If you still get the hang with minimal startup and closedown of Windows,
then perhaps the driver for your VGA is suspect.
