Installed new RAM now computer wont start up

I just installed 2GB of RAM in my iMac and removed the 512mb card it had originally.when i pressed the power button it beeps fast a few time then the fan starts working really fast. The screen doesnt turn on only the sleep light blinks as the fan runs. I replaced one of the new cards with the original 512mb card and it starts but when i check the memory the slot where the new 1GB card appears "empty" why could this be? did i install incorrectly?

When you install new RAM you have to push much harder than you think you should. You won't damage the RAM, but you have t give a mighty push to seat it, make sure you hear a click.

Installed new battery, now computer is extremely slow

Hello,
My battery was DEAD, and I just installed the new one today. (It isn't the one from apple, but Read reviews that this was good so I got it). But I installed the new battery today, and every since, my computer gets really slow and starts to lag a ton after 5 mins of starting up. I've never had this problem before. I tried the smc reset (not sure if it is actually resetting). I did a pram reset as well. I also have a lot of space. It is even slow and laggy when I am not running any programs. Once I start a video, for example on skype, or on youtube, it lags like crazy.
Please help me fix this.
Thank you!

Try having a technician install a battery made for your device.
Using things not made for your computer (or approved by the manufacturer) is a poor way to save money.

My iPod went flat while installing new iOS now it wont even charge. Is there anything I can do????

My iPod went flat while iOS6 was being installed and now it shows a white screen when charging but wont take a charge. Is there anything I can do??????

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Installed new ram, computer wont start up

I installed 1gb of hynix ram. I tried setting it in different ways, but each time when i start up the computer it doesnt even get to the chime sound, the screen doesnt come on, my fan just runs loud and fast and nothing happens, but it starts up fine with out the ram. is there any hope of installing this ram?

Generally if your computer won't start up after you have installed new RAM, either you have purchased the wrong type of RAM, or it is a bad module.
As long as you are able to start up normally after removing the new RAM, and it is supported, it might just be a bad module. Contact Hynix to arrange for a replacement.

i upgraded to yosemite last week, now my computer wont start. it stops at white screen with apple logo. what do i do?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

4 hrs later - Computer shut down after installing new RAM (mid 2007 Imac)

Mid 2007 imac and I installed new Ram. It worked for 4 hrs then the Imac shutdown. The pressed power button but no power. Unplugged and replugged the power cord and 3 beeps sounded. I am wondering if it worked for 4 hrs or so, then why did it would it fail 4 hrs later?
I am running the correct ram because in system profiler under memory - it said that everything was ok.
Any ideas?

or maybe the back tray wasn't tight enough?
I re-installed it now and so far so good.... I pressed tight and in an upwards motion. We'll see what happens

Satellite U400-14B shuts itself off and now it wont start up

Hi
just got a new Satellite U400 this week.
Was working perfectly the first few days, then last night, it just shuts itself off and now it wont start up.
I press the on button and the row of lights next to it light up, but nothing happens I dont even get as far as the Toshiba screen.
I have tried many things. I left it plugged in overnight, tried taking the battery out and no result as of now.
The little led lights on the bottom indicate that there its plugged in, the battery is white not orange, when pressed they all light up again only for a split second.
The only thing I can liken this too is when a car wont start and you keep turning and turning the key, well in this case pushing a button, and nothing happens, the fans dont whir or anything...
help please...

Has extra Memory (RAM) been installed? Try removing one Memory Module and try a different Memory Slot.
If bad memory is not the problem, then there is not much else you can do except send it to an ASP for warranty repairs.

Mac pro put in new ram now none of the ram works

mac pro put in new ram now none of the ram works
it just hangs on restart
the ram worked great for 12 hours then the computer restarted on its own
since then it hangs on restart and never gets to the desktop

It may not have anything to do with the RAM, or it might.
Not enough to go by to say for certain, and the blunt "get new RAM" doesn't address how to troubleshoot or resolve most likely.
Was it installed properly?
How much did you install?
Make? vendor.
Try running with just the new RAM.
Run Apple Hardware Test - boot 'd' key on startup, you may need your OEM Install DVD.
Run Rember and/or Memtest utility to test memory, or TechTool Deluxe.
When a computer restarts on its own it often means there was a kernel panic or something and damage to files, directory, journal and in need of repair, booting off your DVD or another drive to repair the drive, delete some files, turn journaling off and then on.

Computer wont start up

So today I went to start working on my LR and FCPX projects and when I got to the office for no reason at all my computer wont start up.
I've tried holding the "shift", "command" & "V" key from what I read to do, and now I get a black screen which pretty much said what the grey screen said.
This is the strangest thing.

According to your profile your Mac has v10.8 installed.
Startup your Mac while holding down the Command + R keys so you can access the built in utilities in OS X Recovery
From there you can repair the startup disk if necessary or restore OS X.
Hopefully you had all your important files backed up in advance just in case.

Error 8062 when I try to copy or move files on my macbook: "This operation could not be completed because an unexpected error occurred (error code -8062)". Can even not install new software now!!

Since a few days when I try to copy or move files on my macbook, I often get an error message saying "This operation could not be completed because an unexpected error occured (error code -8062)". And then it just quits the copy or move.
I searched a lot on the internet, but only found solutions for cases you cannot empty the trash due to this issue.
I tried those solutions for my trash and that helped after some trying.
However, I still have the problem with copying and moving files.
I even cannot install new software now, as it has to copy itself to the programs-directory, and gives the same error-message.
Who can help me??
Cannot seem to find any info on it on the support-forums or elsewhere.
My user-account is administrator, I use a 13" Macbook Aluminium (Late 2008). Mac OS X 10.6.8 CPU 2Ghz Intel Core Duo, RAM: 4GB 1067 MHz DDR3.
Any help would be greatly appreciated...

Tips I received so far (thanks to A-Mac via Twitter http://www.a-mac.nl and Remco Kalf http://www.remcokalf.nl/)
- make sure you have at least 10% of your harddisk in free space (I had only 5%).
- do a PRAM-reset (http://support.apple.com/kb/ht1379)
- perform a hardware test (http://support.apple.com/kb/HT1509)
- make a complete backup (with for example Carbone Clone Copier, see http://www.bombich.com/)
- after complete backup: use diskwarrior (boot from Diskwarrior DVD, first perform diagnostics, then perform "Rebuild" which rebuilds your file directory).
So far I only cleared up some space on my HD, and already the problem occurs less.
Still, I will go through the other tips too.
(will post progress)

I connected my ipod before installing softwear and now it wont work

i connected my ipod before installing softwear and now it wont work...like abosolutely nothing...its frozen

First of all, try resetting the iPod. It may take several attempts and is best done connected power.
Then download the iPod Updater, install this to your computer, restart the computer, run the Updater, then connect your iPod when prompted (not before), then follow the set up procedure.
