I would try the following:
Modify CONFIG.SYS as follows:-
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE RAM AUTO X=B000-C800
and the last line, to
DEVICE=C:\UTILS\CDROM\GSCDROM.SYS /D:MSCD000
Modify the last line of AUTOEXEC.BAT, to
C:\UTILS\CDROM\MSCDEX /D:MSCD000 /E /L:E /V

This lot, will load both the CD-ROM drivers into _low_ memory, but use EMM,
for the buffers for MSCDEX. It will also exclude the whole of the video memory
area, from use by the memory managers. You do not say what video card you
are using, but a lot of video cards, use more memory in the upper memory
area, when operating in Windows, rather than DOS. These cards, usually
tell you in their 'README's', to do an exclusion, like that above. I have also
seen some CD drivers, that don't like working in the upper memory area,
hence the solution shown. In fact this gives more free memory that the other
solution, if a larger number of buffers are being used by  MSCDEX. It is one
of the 'bugs' of MEMMAKER, that it insists on trying to load MSCDEX high.
From the GPF's, and other bugs, I suspect that something behaving badly,
in your upper memory area.

Good Luck
