Sound output on iMac not working, any help is appreciated

1. my speakers were always plugged into my iMac and it was always working until just now
2. sound was coming out from the internal speakers (or inbuilt speakers on the iMac)
3. tested my external speakers on iPad2, iPhone4 and MacBook Pro, everything works.
4. tested another set of speakers on the iMac, fail.
did i miss out any troubleshooting steps?
please help.

Did you check whether the sound was actually turned on for those speakers in the systempreferences?

    It sounds like you may have multiple problems, but none of them are likely to be caused by malware.
    First, the internet-related issues may be related to adware or a network compromise. I tend to lean more towards the latter, based on your description of the problem. See:
    http://www.adwaremedic.com/kb/baddns.php
    http://www.adwaremedic.com/kb/hackedrouter.php
    If investigation shows that this is not a network-specific issue, then it's probably adware. See my Adware Removal Guide for help finding and removing it. Note that you mention AdBlock as if it should have prevented this, but it's important to understand that ad blockers do not protect you against adware in any way. Neither would any kind of anti-virus software, which often doesn't detect adware.
    As for the other issues, it sounds like you've got some serious corruption. I would be inclined to say it sounds like a failing drive, except it sounds like you just got it replaced. How did you get all your files back after the new drive was installed?

    If you are running Lion or Mountain Lion, the drivers are downloaded from within Bootcamp Assistant. If you are running Snow Leopard the drivers are on your Snow Leopard install disk.

    You need to restore.
    Everything should be on your computer, so you can just sync it back.

    I have an iphone 4s and i keep getting an error message when ever i try to activate i have already restored the phone and it still will not work. any help would be greatly appreciated

    Activation issues are almost always the result of a device that has been hacked or jailbroken.  If that is the case, no support can be provided here.

    A reset has nothing to do with Internet access or data access.
    A reset is simply pressing and holding the home and power buttons until the white Apple logo appears.
    What are you really trying to do?

  • Hello, delete all of my iphone 3G SHSH and now does not work. any help?

    hi, my iphone 3g not reading, accidentally delete all SHSH, i nedd help.

    If it's happening on all the apps that you've downloaded from the App Store, but not the Apple built-in ones, then try downloading any free app from the store (as that appears to reset something) and then re-try them - the free app can then be deleted.
    If it's happening on all apps including Apple's, then try closing them all completely and then see if they work when you re-open them : from the home screen (i.e.not with any app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of each app to close them, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
    If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • Trying to install Flash 11.5 on Mac OS X 10.6.8. Install completes but Flash does not work - any help?

    Hi, I was told I didn't have Flash 7 when trying to see something online (which I am sure was incorrent to begin with) so I followed the provided link to download Flash version 11.5. The download completed without problems but Flash doesn't seem to work at all. I have uninstalled, reinstalled and restarted. I don't know what to try next, any help would be much appreciated!

    Start here;

    Also, never, never follow links for flash, codecs or plug-ins of any kind from websites that throw up these warnings - there's a high chance of the link being to a malware site.
    Always go directly to the vendor.

    Not enough info in your post to help, such as your Messages settings and whether or not you have a data connection,  Have no idea what you mean by "Apple system statem"
