Have you tried the Autoconfigure?
If not...from desktop click on START
run up to PROGRAMSEA GAMESMOHAA CONFIGURE.
it should state the recommended configuration from what its read from your system.check to make sure it reads 64 megs available on the graphics board,I had a problem with my mx400 after I tried detonator drivers.config only read 40 megs.
I installed original drivers...runs great.
Also config told me my mx400 was in fact a mx200???what about that,this board came from PC WORLD!!!installed 200 drivers, runs great 1064*768 32bit ,also ,to get fullscreen,click and check the fullscreen box in optionsvideo with a red cross...and read Manny's exellent tweaking guide.
