"Terminating thread due to a stack overflow probelm. a
VxD, possibly recently instealled, has consumed too much
stack space. Increase the setting of "MinSPs" in
SYSTEMINI or remove recently stalled VxD's. There are
currently 5 SP's allocated."

I did not install any additional hardware or software.
My computer is acting up. It freezes and goes into
recovery mode. I have powered down twice and re-entered
my password - very carefully. Ran a system scan - no
viruses found.
It does not shut down properly - freezes at Windows 98
screen. When I do power up I would get the above blue
screen.
