Thank you for the information.
The bits that lead me to think it is 32 bit drivers being used:
The EMU files are installed into program files (x86)
Crashes identified the culprit as HA10KX2K.sys found in the system32\drivers folder
WhoCashed reported it was the ha10kx2k.sys file
mostly it seemed to refer to the MIDI driver
I have a note that the WDM driver was listed at least once
HA10KX2K.sys is identified as being the HAL WDM driver.
I do not have a current minidump so I cannot describe what other info was available.
I think I have not had a crash since I installed the new OS disk in September.
The driver package I installed is:
