From time to time my imac is switching off all of the sudden, who knows what it could be?

Once every few days my imac (2010) is switching off all of the sudden. It is happening since a few weeks. Who knows what it could be?

Hello Tommy,
Have you blown the dust out lately?

1st Generation iMac G5 shuts off all of a sudden

My iMac G5 keeps shutting off all of a sudden. Also when I turn it on it shuts off 2 out of 3 times in about 5 secs. anyone have any ideas on whether this is a hardware or a software problem?
I had the power supply replaced through the warranty agreement about 2 yrs ago.

I too have a rev a imac and I too had problems a year ago, with kernel panics and sudden shutdowns. I took it for repair after noticing capacitors bulging and leaking, just to the right of the power socket. The bad capacitors had "x" on the bottom. I was told the mid plane had been replaced and everything seemed to be ok.
Guess what?
3 days ago, it started happening again.
Just now I had a look in the back, and surprise, surprise, there are bulging and leaking capacitors, this time to the left of the power socket. Again the leaking capacitors are ones with "x" on the bottom. All the other capacitors have a "y" on the bottom.
I suggest you take the back off your imac and visually inspect the capacitors.
i am very very annoyed at this situation.
The las fault occured when my imac was 11.5 months old, so I panicked and paid for Applecare. Then I found out that the warranty had been extended on all rev a imacs. Now my imac is one month short of 3 years old, and again this is happenign just before my apple care runs out.
This does not give me any faith in the future of my imac.

Have you tried to reboot your iPad? Hold down the sleep and home keys until you see the silver apple. Let it reboot and try agian.
Also, try power cycling your router. Meaning, unplug it, count to 10, then plug it back in. Let it reboot and see if that helps.

I have face time installed on my iMac but when I go to the app store it doesn't show installed and has a.99c price. All other apps show installed. Is this an upgrade?

The first thing to do: Make a backup of your iPhoto Library. Don't update iPhoto without having a backup of your iPhoto library.
When I tried I received the following message This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled.
This error message means, that you did not yet associate your copy of iPhoto (preinstalled on your Mac) with your AppleID by clicking the "accept" button at AppStore "Purchased" page.
First try to "Accept" iPhoto on the Purchased tab and try, if you then can update iphoto from the Updates tab.
Now check the "Purchased" tab. Is iPhoto among your Purchases to "Accept" or "Install"? Then accept and/or install.
If it is not possible, delete iPhoto from the Applications folder .
(don't empty the Trash).
If it is not among your Purchases, open the AppStore main tab, search for iPhoto using the Search field, and buy it from the AppStore. If you already owned any version of iPhoto '11, this purchase should be free, from earlier versions it may be a paid upgrade.
If all fails there is no help but contacting the App Store Support to sort out the AppleID. Use this link: http://www.apple.com/support/mac/app-store/contact/
I can delete the existing software and re-install but I don't want to lose all my photos.
Your photos are in your iPhoto Library in your Pictures folder and not in the iPhoto application. Just back up the iPhoto Library as a precaution, but reinstalling iPhoto will not delete your iPhoto Library.

Tomcat switches off all the time

I tried to install tomcat 5.5.12 on my windows xp computer. Unfortunately tomcat switches off all the time!!! I can not run tomcat automatically.
What might be the problem? Are there maybe wrong windows settings?

I think you need to look at tomcat websites and forums.

When I open firefox it is returning to the last viewed page instead of my homepage even though I have the settings set to clear history every time I close Firefox. I check and all of the previous history is still there and not deleted..

Make sure that Firefox closes properly and that that there are no longer Firefox or plugin-container processes left on the Processes tab in the Task Manager. Otherwise session restore will reopen the page(s) from the previous session.

I have given up on my dell and bought an iMac 27"... Now how do I transfer my dell iTunes playlists from my dell to my iMac, as they are showing on the iMac when I plug in my iPod but it's not allowing to me to play them as they are shaded? I have also separately transferred all my music via my external drive from my dell to my iMac which is showing in iTunes but won't upload to my iPod... Just to confuse you even more my AppleTV which is linked to my log in email address and home sharing is showing and playing all the playlists I want to see on my iMac... Phew that was exhausting hope you understand and can help me:-)

You may have transferred all your songs, but your iPad is seeing the library as a different entity.
The following article(s) may help you.

I do something like that, and can confirm 20 feet won't be a problem. More than 30 or so might be.

I have 2? How do I sync selected photos from my IPad to my IMac w/o losing all photos on my IPad and getting the phoos o my IMac. ou see I have two IMacs with different sets of photos. Also want to convert all Apple works docs to pages docs on my IMac.

I have 2? How do I sync selected photos from my IPad to my IMac w/o losing all photos on my IPad which will be replaced with the photos on my IMac.You see I have two IMacs with different sets of photos. Also want to convert all Apple works docs to pages docs on my IMac. Is there and app available to do the former. many thanks. b

The iPad and related software is designed to sync with only one computer. I suggest transferring the photos from one of your iMacs to the other so that all photos are on one Mac. Same for all other files you want to sync over.
To get those AppleWorks files to the iPad you'll have to determine if Pages will open them. If it will then use the file sharing feature of iTunes to copy them to Pages on your pad.
If Pages will not open the AppleWorks files directly you'll have to save them in some format that Pages will read. These include but may not be limited to Pages and Word formats.

You can turn Find My iPad 'off' by going to http://icloud.com and logging into your account, select the iPad from the device list in the 'Find My iPhone' section on that site, and 'remove from account'

You are not specific with your problem or errors but one thing that always throws people off is as follows:
When entering you're login name you must use the entire login with carrier name such as [email protected] The field defults to just your name but not the carrier name.

From time to time my imac is switching off all of the sudden, who knows what it could be?
