assistant: Hi, Dennis.  The usual reason for this kind of instability after the
machine has been running for a while is a defective cooling fan.
Things to check:
1. Many machines have cooling fans on top of the CPU itself.  Over time,
   the fan may get clogged with dust, and then the CPU overheats.
   An overheated CPU commonly goes flaky and eventually stalls completely.
   This forces the user to shut down the machine, and by the time the
   user restarts, the CPU has cooled enough for it to run reliably for
   5 minutes or so before starting to go flaky again.
   However, you can't predict exactly what an overheated CPU will do,
   each CPU fails in a different manner.
   Regardless of how the CPU fails, one of the common things that
   happens is the flaky CPU interferes with reliable W95 Registry
   housekeeping.  Eventually, the overheated CPU decides to do
   something flaky while W95 is writing to the Registry, and you
   get Registry corruption as a result.
   The usual solution to this problem is to disassemble the machine
   and clean the CPU fan.  In some cases, the CPU fan bearings wear
   to the point the fan no longer spins reliably, and the fan itself
   must be replaced.
2. All machines have a fan which draws air through the Power Supply.
   If this fan fails, the Power Supply itself overheats, and the
   power supplied to your motherboard can become unstable.  This
   unstable power can also affect other components such as your
   Hard Disk drive.
   The usual solution to this problem is to replace the Power Supply
   fan.  In some cases, it is less expensive to replace the Power
   Supply as a module rather than disassemble the Power Supply and
   replace the fan itself.
Hope this helps.
Best I can do for now. <tm>
Bill
