HT2248 G5 will now not recognize 2 added dimms that have worked perfectly for 3 years

Added 2 x 500 dimms 3 years ago, has been fine up until recently. But now the computer is running very slow and have discovered it is not showing or recognizing that the extra memory is there. It is showing only the original 2 x 256 dimms and nothing in the other slots. Anyone experienced anything similar?

Take a soft gum type eraser and rub the contacts on the RAM.
Look at this link: Testing RAM @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.
Do you have an Apple Hardware Test disc? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.

My new Dell PC running Windows 8 does not recognize my iPad or iPhone. Worked OK for iPhone for months but would not work for new iPad. I removed /relaoded iTunes and now it won't recognize either iPad or iPhone.

HT1551 My Apple TV has been working perfectly for a year now it doesn't.

My Apple TV has been working fine for a year, and now it plays about a minute and "An error occurred loading this content" screen comes up. This has been going on for 2 months.I tried to use it with Netflix and with movies purchase through the Apple store. Iphone sych also does not work.

Hi Brian - The light at the front of the ATV indicates it is on. I can't see it on the iOS remote app. Actually, I installed the app and when I went to the ATV it said 'no signal'. So, I am not sure if it is coincidence or what, as I did NOT go to the settings on the ATV and change the remote setting. I can't set it to another TV, can I set it to my MacBook to check? Thanks a lot by the way!

Import does not recognize old image files that have no extension

Just discovered that the import facility does not see (or accept) old Mac image files that have no extension -- even if these files have a Mac "kind" that is an image such as "Adobe Photoshop file".
You can manually add an extension to the file (and respond to an "are you sure?" dialog). Then the file will be seen and accepted.
This is extremely dangerous (and painful to manually correct) since you think you are seeing all images in the import box, but you are not.
In fact, I deleted huge image directories after having satisfactorally (I thought) imported them into Aperture many months ago. Most of the old extension-less files had been updated and did have extensions in later versions. However, I missed one important image and looked everywhere for it.
By a miracle I had a backup of my image directories on a Power Book that I am retiring and finally noticed that the missing image was there just before deleting that directory too! I then figured out why this image (and many others) had not been imported. So, now I am going through manually and adding extensions.
Does anyone know a better way -- to get Aperture to recognize extension-less images? If not, this needs to fixed in the next version as it is a disaster waiting to happen.

Well there's an idea...probably would need to go into Bridge <g> to do that most efficiently .. or Automator.
It turns out that I already had added extension to most (but not all) images in my main image directory and so they got into Aperture alright. I just have to go through all the images in the backup I just found (where many did not get extensions) to find the ones that Aperture missed. So far, there have been just a couple more...
The real problem is that Aperture should not be missing these, even if they are archaic. At the very least, Aperture's import should give a warning that there are files in a folder that it is not going to import AND is not even showing. Otherwise this is a serious gotcha!

TS1722 Have lost ability to open Boot Camp on start up or restart. Only Mac icon shows up. Worked perfectly for two years and now it implodes. Any hope of re-opening Boot Camp?of recapturing data in

Have lost ability to open Boot Camp on start or restart. Icon does not show up. Had been working for 2 years, then nothing. Recently had problems with Kodak Easy Share in PC partition. Any connection? Any hope of reopening Boogt Camp without losing data already there?

Can you see there is a partition?
Can you boot Windows 7 DVD?
Did you think you would never need a backup image?
So no Safe Boot, no F8, possible?
Paragon CampTune
Paragon CampTune is a commercial product that is designed expressly for this task. http://www.paragon-software.com/home/camptune/ It consists of a downloadable ISO that needs to be burned to a disc and booted from in order to resize the partitions. During testing it was available free, but now costs US$19.95. MR user Rodus reports that it damaged their OS X partiton and a reinstall was required, so heed the warning and have a backup.
Paragon Partition Manager
From the makes of CampTune is a commercial tool that is similar in functionality to GParted Live, but has a more polished/friendly user interface than GParted Live. Previously only the US$79.95 Professional version supported all the features required for this, but as of version 11 the US$39.95 Personal version has also been reported to work. http://www.paragon-software.com/home/pm-personal/
Securing Dual-System Configuration
Imaging is still the most affordable and robust way to secure computer data. Unfortunately Mac OS X backs up only HFS+ volumes, leaving Windows with dual-system configurations unsecured. You can permanently lose all of your data unless you have a Windows-compatible backup solution.
Paragon’s CampTune and Paragon’s Drive Copy for Mac can secure the entire dual-system configuration. CampTune creates traditional images of volumes or entire hard disks, Drive Copy can copy them to other disks. In case of an emergency, you can restore the previously created image or copy all your data back to its original state.
Winclone/Disk Utility
Winclone is a free tool for creating and restoring backup images of your Windows partition. One of its key features is that it can restore to a larger partition than the one the image was created from.
NOTE: Winclone has been discontinued, but for now remains available and capable of completing these tasks (including creating and restoring Windows 7 images).
Winclone updated to support Lion Winclone updates and download
Disk Utility can resize HFS+ (Mac OS) partitions, but is currently incapable of resizing NTFS partitions, so you could use it to reduce the size of the HFS+ partition and create a new larger placeholder MS-DOS (FAT) partition
The full process would be:
Backup Windows partition with Winclone.
(if the new Windows partition is smaller than the old one make sure you set the preferences in Winclone to save the image as an uncompressed dmg)
Delete old Windows partition
Resize current Mac Partition
Create new Windows partition as MS-DOS (FAT) in free space after Mac OS partition.
(If the new Windows partition is smaller than the old one an additional step is required: shrink the filesystem on the image by selecting Tools->Shrink Windows (NTFS) Filesystem)
Reboot your computer for the new Windows partition to mount properly (winclone may not restore if you don't reboot)
Restore Winclone partition over new Windows partition
An alternate Winclone based process is described in the External Guides section

Hi! My "Touch" has gone haywire since a botched up date. The colour has gone from my music menu Page (eg "songs", "artists2 etc. and my Touch will now not shuffle my tracks so I have to move on manually. Help please.

An update to my Touch went haywire and I lost my music and apps but luckily I had subscribed to i Cloud and they were reinstated but my music contents page - "artists", "songs" etc. no longer has any colour and the shuffle will not work. Help please?

Yes, the color has been deleted iOS 6.
You have tried turingin on shuffle, right?
Try:
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.

I have updated to firefox 5 from 4.01 i use talktalk for my e mails this will now not open it tells me i have undefined mails in box have tried windows explorer this works ok can you help me to get talk talk to open worked fine on 4.01

is there anything that is stopping my mails from opening

Have you tried the trick of setting Firefox to ''lie'' to TalkTalk mail by saying that you are still using version 3.6?
You can find the instructions for that in a post on the TalkTalk forums: [http://www.talktalk.co.uk/forums/showthread.php?t=185113#post2452787 Firefox 4 & TalkTalk webmail - Forums].
Note: when you open about:config the first time, it will display a warning message that you should be careful with the changes you make. That's definitely good to bear in mind.
Does it work?

My Iphone 3gs has turned itself off and will now not come back on! I have connected it to the laptop and tried rebooting it but nothing is happening! Any suggestions please???

Help!!

My I Phone 3GS did exactly the same. Tried holding the buttons, syncing it to my laptop, plugging it in to the mains (it didn't even beep).
I rang my service provider (Orange) but they couldnt fix it. They passed me onto Apple. Who went through everything. But no joy.
Apple sent me a box to return my mobile to them. Now I have no mobile and have to wait to hear from Apple..
I'm gutted cause no mobile now :-((

I have a time capsule that has worked flawlessly for several years. I recently upgraded my iMac OS to 10.8.4 and coincidently (or not) have started having some issues with backups. When I go into time machine, it struggles to find the time capsule disk

I have to unplug my time capsule and reboot it. Is there a diagnostic routine I can run or any error detection I can look for?

You are absolutely right.. when apple changed significant features in Lion and Mountain Lion .. they introduced a bunch of issues into networking which are bugs to this day..unacknowledged.. and without much that will fix them.. other than your reboot strategy.. which is like.. well that other OS.. where continual reboots are considered normal.
Old TC may also just suffer from age.. we continually tell people they have a lifespan.. 3years is the reliable span.. after that expect anything.. sudden death.. slow decline.. continual hassles and problems. If the backups are important to you.. then it is telling you in a very clear way.. replace me.. I am no longer happily providing services promised.
Now to specifics.. we don't know what the problem is.. if we knew we could give some work around.
The problem is odd in that it doesn't affect everyone.. if it starts .. people find it starts several months in to ownership.. it is never cured.. or even curable.. something like DNS or ARP table is being lost.. but it is not either of those things.
Is there a diagnostic routine I can run or any error detection I can look for?
Nothing much shows up anywhere. Including the TC log or local logs. It simply has lost the TC disk but not internet.
So.
Some things do help.
I don't know if you have pondini's resources.. TM is a complex piece of software.. it has multiple issues.
http://pondini.org/TM/Troubleshooting.html
Look at A1 .. load the widget.
A5 .. verify the backup.
A4 .. reset TM.
All of those things can help.. look at some of the typical problems.. C12 and C17 being the most common since Lion.. and exacerbated in Mountain Lion.. not fixed.
Some suggestions.
1. Keep names short, no spaces and pure alphanumeric. See C9 http://pondini.org/TM/Troubleshooting.html
2. Do not use 7.6.3 firmware... go back to 7.6.1 or even better 7.5.2 on an old one.
Firmware downgrade is easy in new utility. Hold down the option key whilst selecting version.
3. I recommend a very short dhcp lease time.. 20min for example. In whatever device is the router .. that can help keep things up to date.. and use dhcp reservation again to see if the address info helps to keep things updated.
4. Do turn on ipv6 local link.. which you need to anyway with 6.3 utility.
http://support.apple.com/kb/TS4597
5. If you are using a desktop.. an external drive is faster.. more reliable and easier than TC for Time Machine backups..
6. Consider using CCC or another backup software.. if you want to continue to use network drive.
7. Although using 6.3 airport utility has some advantages.. it is also devoid of a lot of tools that are in v5.6 airport utility.. well worth loading into at least one computer on the network.. if you only have Mountain Lion now here is one method.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
Leave the package open on the desktop so you can see the file. AirportUtility56.pkg
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. If your Mac refuses to run the software, because it wasn’t downloaded from the Apple store, go to security in preferences and allow other software to work.. this is limitation of trade methinks. You can set back later if you like.
Now drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. in finder, open the new directory, drill down.. applications, utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall version 6 (now 6.3 if you updated) so don't try.. and you cannot or should not run them both at the same time.. although I have had no problems when doing so.

SIM not provisioned on an ipad that has been operating for five years, help

My ipad was installed at the same time as the MacBook Pro 5 years ago; I've never had to do anything with it other than upgrading the software (hook up to the MacBook Pro). Now it shows "no service" and the network shows "sim not provisioned." I wrote the sim card number down. Can you tell me how to proceed from here?

You need to use the Transfer Purchases function in iTunes and then sync the iPad mini. Back up the application.

hi i was using safari one day and my ipod randomly shut off it will now not turn back on i tried hard resting and everything else when i plug the ipod into a charger it gets really hot in the left corner and itunes did not recognize any help will be apreciated thank you

Try placing the iPodin recovery mode and then try to restore the iPod via iTunes on your computer. For recovery mode see:
iPhone and iPod touch: Unable to update or restore
Next would be to make an appointment at the Genius Bar of an Apple store since you likely have a hardware problem.

When I recently updated FireFox, the DownloadHelper add-on was lost, and will now not download, though I have tried about 5 times??

When I recently updated to the newer version of FireFox, (version 3.6.13) the DownloadHelper add-on was lost, and it will now not re-install, though I have tried about 5 times?? When I clicked the icon to download the add-on the download progress bar indicated that the download was underway however, when it had completed, the add-on appeared not to have downloaded - including no icon - not even if I search for one. When I tried to download the same add-on again, the download window indicated the download in a faded color and it seemed to be indicating that I already had the add-on. Try as I might, I can't get it to work. DownloadHelper always worked with no trouble on the previous version of FireFox. Are you able to help? Many thanks for this service!

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (Firefox 4: click the Tools button at the left side of the Search Bar) to do a compatibility check.
You can also try "Reset all user preferences to Firefox defaults" on the [[Safe mode]] start window.

My Time Capsule expired and no longer works. My printer (a HP) will now not work as it still wishes to connect through the Time Capsule. It will not allow itself be recognised through a USB connection to my Mac. Anyone got any ideas?

My Time Capsule expired and no longer works. My printer (a HP) will now not work as it still wishes to connect through the Time Capsule. It will not allow itself be recognised through a USB connection to my Mac. Anyone got any ideas?

You will need to install the printer on your Mac
Open System Preferences (gear icon) on the dock
Open Print & Fax
Click the + (plus) button at the bottom of the printer list
Wait for your printer to appear in the next box, then click it to highlight it
Click Add at the lower right
Be sure to select the correct printer when you try to print as you will see your printer listed twice. Good idea to make the printer now installed on your Mac the default printer so you do not have to choose which printer to use each time you want to print.
You can also go into Print & Fax, select the printer associated with the Time Capsule and click the - (minus) button if you want to delete that location.

The word app has disappeared from my desktop computer and can't be found on finder or search. All documents I created on word will now not open unless in "TextEdit" format which I don't use. Any ideas please? Thanks

Did you recently erase and/or reinstall the OS?
And, some details are needed: model/year Mac, Mac OS version running now and which version originally).
