Here.
My problem was resolved by
Disable fullscreen optimizations in the proprieties of SH3.exe (right click mouse).
Sh3 and Sh4 after a clean instalation would work fine the first time, but after a shutdown or a reboot, I had the black screen of death in Sh4 and CTD in Sh3.
After doing what is in the link below, my problems disapeared.
Also, the same thing in SH3 comander.exe and have the latter in running as administrator.
