Problem with our Apple Macs shutting down

\015 We have 5 dual processor IMac's that run on a network in our offices and we have a problem with them shutting down. Please can you give us a solution to this problem, we can't understand why they battle to shut down in the evenings even when we've disconnected all our machines on the network before closing. Help please. Thanks.I have an iMac it was working fine, actually it's the computer my kids use to do their various learning skill on. My 7 year old daughter was bringing up various things onto the desk top...and I dragged them into the trash to remove them off of the desk top...well after that the computer shuts down every time I turn it on...and I'm not sure what the problem is...it will not stay on...I tried pressing the reset button and it still continues to shut down right after I turn it on....please, HELP! \015\012\015\012It's one of the dome shaped iMac's it's a 1999 iMac.\015

A quoted suggestion from my Mac Guru: "They need to turn off the Energy saver preferences for processor\015\012cycling and hard drive spin down. They would actually be better off\015\012turning them down anyway since the G5 duals run really hot and aren't\015\012the most reliable model Apple ever shipped for motherboards failing."

As for the iMac 99, It would be more helpful to know what OS the unit is running. I remember hearing a story about a disgruntled employee putting the 'shut down app' in the start up items folder. This caused the Mac to start as normal and then shut down after the startup was complete. Try starting up the machine with the extensions off. 'Hold down the shift key at startup'

I was kindly given an Apple Multiple Scan 17 Display the other day, which has a peculiar problem. The very first time I plugged it into a Mac, I turned the both of them on, and saw the happy Mac for a split second on the display, then it went out! The power light on the display turned off! After disconnecting it and trying to turn the display on a few more times, it appears that as soon as the degauss is done, the click sound, the monitor just shuts down. Anyone have any ideas about fixing this?
