Problems with sleep and startup on beige G3 w OS 9.2.2

I recently did a clean install of system 9.2.2 on my beige G3 desktop. Now, if I leave the machine on long enough to go to sleep, it hangs up and needs to be restarted. Also, when I start it up from cold with the power key, it hangs almost immediately, needing a restart with control-command-power key, and then functions properly.

This is an annoyance only, so I haven't tried another re-install. Are there some settings I should be checking to fix these problems?
