Sometimes DOS games reboot your computer if they run out of whatever type of memory they're using or are having some sort of difficulties with your hardware. Are you playing in DOS or Windows?
There is a patch called Sherlock.zip here
Here's what it says in the readme:
The Sherlock Holmes 1.02 update corrects the following problems:
o Screen flashing in the video player would occur with old VGA cards on slow PCs.
o Setting the sound card to a DMA channel other than 1 would cause Sherlock to lock up or mute the audio. You can now set the DMA to 0, 1, 2, or 3. Please refer to your sound card users manual for directions on changing the DMA channel.
o Setting the Sound Blaster Pro's interrupt to 2 or 10 would cause Sherlock not to recognize that a sound card was installed.
To use the updated version of Sherlock, copy the SHERLOCK.EXE file included in this package onto your hard drive or a floppy disk. Change to the
directory where the new SHERLOCK.EXE file is located and type "SHERLOCK". The program will automatically find the CD drive containing Sherlock Holmes.
If this update does not fix your problem, please contact ICOM Simulations Technical Support by phone at 708/520-4440 between 9AM-6PM CST, by fax at 708/459-7456, or send mail any of the following accounts:

I don't know if this will help with your program or not.
