Hard to say without more model info. For a start, please do "About this Mac" from your Apple menu and tell us what processor info is shown in the resulting window (line indicated by lower red arrow):

Why does my iMac display go off when I am starting up or waking up my machine from sleep..

Why does my iMac display go off when I am starting up or waking up my machine from sleep..?
When my iMac goes to sleep I then later try to click the magic track pad or keyboard and it will usually then show the initial password entry login screen and then go off. The machine is still on but the display is black and will sometimes flash up the screen again if I press the magic track pad or keyboard but will then black out again..

Well, there are many different reasons why it does this. It might shut off due to power voltage problems, system overheats, or there is a System Problem. The reason it might be hard to boot up is because your power button might not work properly or your system hard drive is damaged.

Why is my imac so slow browsing

why is my imac so unbelievably slow.I have a gig of ram?

"I have a gig of ram?"
What are the other specs? Processor speed? Free space on hard drive?
Is the slowness limititd to some sites?
Slow choppy web video is the most common complaint, and there is not much you can do about that. The newer video technology is optimized for Intel processors. That aren't many G4 friendly vidoe web sites around any more.

Why will my Imac (1 yr old) only print the full document in half a page?

Why will my IMAC only print the full document in half a page? All updated IOS downloads. My Laptop Mac does not do this, so I feel it is not the printer, but the actual computer. The full document is printed, it is just half a page, other half is blank. This is presenting a huge problem for school and also when I need to print a shipping label ( which I do often) for my business. I have several printers and it performs the mistake on all of them. Thank you!

Make sure the scale in the Print window is set to 100%

Why does my iMac only have 1 GB of memory? I hardly have anything on here. I cannot download software update in order to get Turbo Tax to work.

Why does my iMac only have 1 GB of memory?

Put in more RAM. Visit OWC, DataMem, or Crucial.com to purchase memory for your model. You computer would have more memory had you put more in a long time ago.

Why does my iMac appear many times in my network and labelled 1,2,3, etc

why does my iMac appear many times in my network and labelled 1,2,3, etc

Ok, I solved it.
I followed this steps:
1- Turn Off Wi-Fi from the Wireless menu item
2- From the OS X Finder, hit Command+Shift+G and enter the following path:
/Library/Preferences/SystemConfiguration/
3- Within this folder locate and select the following files:
com.apple.airport.preferences.plist
 com.apple.network.identification.plist
com.apple.wifi.message-tracer.plist 
NetworkInterfaces.plist 
preferences.plist
4- Move all of these files into a folder on your Desktop called ‘wifi backups’ or something similar – we’re backing these up just in case you break something but if you regularly backup your Mac you can just delete the files instead since you could restore from Time Machine if needed.
5- Reboot the Mac
6- Turn ON WI-Fi from the wireless network menu again

Why does my iMac display keep shutting off? Computer still running in the background. I've tried unplugging and restarting, to no avail.

Why does my iMac display keep shutting off? Computer still running in the background. I've tried unplugging and restarting, to no avail. The computer is well out of warranty - about 7-8 years old, running 10.6.8

Checked.... the settings had not been inadvertently changed, but I did move the scroll and reset them back to the original. Hasn't shut off again.... yet. Will re-post with follow-up one way or the other. Thanks.

Why is my iMac hyperactive?

Again I ask, "Why is my iMac hyperactive?" My iMac scrolls a-little all on its own, that is with _zero_ input by me. Maybe my Apple Magic Mouse is just _too_ magic?
Here at this Very Window, my iMac scrolled all on its own. (Please trust me.) Get Back Here!
Lastly I ask, "Does anyone else Notice this problem?" Thank you.

OK, something else then...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Why does my Imac screen slide and I lose my screen? It goes back to my desktop. Then sometimes my screen goes to full screen and I don't know how to get out of it.

Why does my Imac screen slide and I lose my screen ~ It goes back to my desktop.
Then sometimes my screen goes to full screen without me doing any commands, and I don't know how to get out of it without going to force quit and starting all over.

Hi,
When it goes full screen try moving the mouse up to top right of scren & see if there a double diagonal Arrow to click on.
On the other see if it's the silly implentation of Spaces/Mission Control/Expose in ML...

Just updated details - os x 10.8.5 .....
found an answer that could have been problem with CPU and a runaway application (possibly Bin Weevils) which my son was running at the time. I shall check the activity monitor next time to see what percentage cpu is being used..

Why my new iMac won't read my external hard drive?

Why my new imac won't read my external hard drive??

Liz,
Sorry for not responding sooner, I support your position completely - as for the external drive I assumed that the individual was a previous mac user and knew about that (my mistake) at home I have a couple of external drives
one drive is acknowledged regardless of format (mac/win) its a partitioned drive.... the other one - far as the mac is concerned does exist when i connect it. I believe its a win only drive (will have to check the specs on it) but it works on the win-notebooks.
so my point of reference was coming that perspective, with no additional posts I have to assume you had the correct answer. have a great day.
