#1 - Best way to turn the computer off when it hangs, is to press the power button for 5-10 seconds. It will then power down. I believe it's a marginally better option than the power plug.
#2 - Open the RAM hatch and look for bad capacitors. Sounds like it MIGHT be them...

Currently Being ModeratedAug 30, 2010 7:59 AM (in response to kourtney13)Welcome!
As the Hobo mentions, some eMacs with 1G and 1.25G processors and USB 2.0 logic boards are plagued with a problem that manifests itself as leaking capacitors. Before going much farther, check your serial number against this list of ranges in which the problem could exist:
• G8412xxxxxx- G8520xxxxxx
• YM412xxxxxx - YM520xxxxxx
• VM440xxxxxx - VM516xxxxxx
When you look in the RAM door as Hobo recommends, bad capacitors can look like this:
The Apple Repair Extension Program that covered the repair at no cost to the owner unfortunately expired over a year ago. The cost to fix is much higher than a used eMac is worth, unless you live in the western US. If you do, there is an option through a firm in Oregon that can repair, not replace, the logic board for a flat fee.

Currently Being ModeratedAug 30, 2010 7:31 PM (in response to kourtney13)Hi,
Yes the last model eMacs 1.42Ghz were over that capacitor defect I think.
There could be many reasons for your computer freezing, but doing a hard shut down like you have may cause some software problems so it would be a good idea to run Disk Repair from the 10.4 DVD just to ensure your OS is back in order.
Procedure is to insert the Install DVD 1 into the drive and then select Restart; when you hear the chime hold down C key until the apple logo appears.
This will take you to the installation software, but you do not want to install.
Select your language, then go up to the top menu bar and navigate to the Disk Utility application.
Select the hard drive on the left, then go to the First Aid pane where you can click on Repair Disk.
If it finds errors, repeat the process until it reports no errors.
After these repairs, quit the Installer, and restart normally.
Once restarted normally run Repair Permissions from the Disk Utility application found on your hard drive in Application/Utilities.iMac (20" 08) eMac (ATI) iBook (G4) 10.3, Mac OS X (10.5.8)
Currently Being ModeratedAug 30, 2010 9:56 PM (in response to kourtney13)I agree with roam--I've never heard of a bad logic board in a 1.42. Nice machine, and the ATI 9600 video chipset supports Core Image so should work with 10.5 nicely if you need it. You can also install the newer 1G RAM modules for a max RAM of 2G. However, you need to buy these larger modules from a Mac-savvy RAM vendor, preferably online. I added one 1G to our eMac 1.42 to give a total of 1.25G RAM. Not a hint of trouble with this much RAM. If interested, post back and I'll link the two online vendors I trust to send me the right thing first time.
If you have never done any maintenance steps, that would be the next step after you get up and running with roam's suggestions. Look at the list of articles on this page:
focusing on those having "maintenance" in the title. Actually, the entire article collection is a treasure trove of Mac happiness.
Has the eMac been unplugged every night, or turned off at a power strip or battery backup? That can drain the little logic board battery (also called the "PRAM" battery) normally used for short-term retention of settings during a power outage or short move. A dead battery can create startup issues in some Macs. A replacement is only US$5 online, and you can access it through the RAM door.PowerMac G4 MDD 1.25G SP;, Mac OS X (10.4.11), ; MacBookPro Late2007 2.2G 15" (10.5.8); PowerBook G4 1Ghz 17" (10.4.11)
i would put the disk in but i can't even get the disk door to open.is there a way to open the drive without just hitting the eject key on the keyboard? i turn it on and get the blue screen that shows up before the start up bar comes on and that's it. i do frequent checks with my tech tool deluxe, at least once a month or more, but have never had any problems or repairs needed.emac, G4 Power PC, Mac OS X (10.4.11)
Currently Being ModeratedAug 31, 2010 2:24 AM (in response to kourtney13)I see, a catch 22 situation.
Will it start in Safe mode?
Starting up in Safe Mode
If you can do that successfully that may be enough.
If you can't do that you could reset the NVRAM

Currently Being ModeratedAug 31, 2010 2:48 AM (in response to kourtney13)i was able to get my computer working in safe mode and am now running a diagnosis on my main volume. thank you very much to everyone who offered help. hopefully i'll be able to take it from here. if not i know where to find you guysemac, G4 Power PC, Mac OS X (10.4.11)
Currently Being ModeratedAug 31, 2010 7:51 AM (in response to kourtney13)Glad to hear you got it running diagnostics in Safe Mode!
For future reference, you can manually open the optical disc tray by holding the mouse button down while starting up. In case that doesn't work as advertised, you can also pry the optical door open with a fingernail or X-Acto knife, then insert a straightened heavy-duty paper clip or #0 hex driver/key into the hole next to the optical tray proper to press the manual eject lever inside the drive.eMac 700MHz, Mac OS X (10.4.11), 640MB RAM ABS Snow LaCie D2 HD; AL iMac 10.4.11 2 GB RAM; LaCie D2 DVD-RW
Currently Being ModeratedAug 31, 2010 6:32 PM (in response to kourtney13)still not working. i was able to load my computer in safe mode and reinstall mac OS X but i still can not get it to load in regular mode. no load bar no asking for my pass word nothing.emac, G4 Power PC, Mac OS X (10.4.11)
Currently Being ModeratedAug 31, 2010 8:54 PM (in response to kourtney13)When you were using the internet the other day and your computer froze, was this after you just installed something or changed something? Can you remember what you were doing at the time. Could offer a clue.
If you disconnect everything except keyboard and mouse will it start in normal mode?
When you reinstalled the OS in Safe mode i presume it restarted OK then. Did you choose Archive and Install or Erase and Install. You may need to do the later to delete some bug in the archived version.iMac (20" 08) eMac (ATI) iBook (G4) 10.3, Mac OS X (10.5.8)
